Poor fertility and low water retention at the different soil moisture constants are both limiting factors of crop productivity in sandy soils. Recycling organic wastes might provide such soils with nutritive elements and, at the same time, improves their chemical and physical characteristics. Thus, two organic amendments (biochar and compost) were selected in the current study to investigate their effectiveness as amendments of a sandy soil while considering the following two assumptions: (H1) efficiency of a half dose of biochar or less is comparable to the effect of the full dose of compost for improving soil physical and chemical characteristics. Furthermore, the residual effects of biochar (vs compost) on soil properties seemed to be more noticeable in the successive growing season. (H2) Biochar can negatively affect the bio-availability and concentrations of P and soil micro- nutrients within the areal parts of plants due to its alkaline nature on one hand, and its relatively high persistence in soil, on the other one. Accordingly a sandy soil (of low buffering capacity) was amended with either biochar (BS at elevated rates) and/or compost (CT), solely or in combination and then planted with peanut. The residual effect of these amendments was investigated in the successive season on wheat. Results revealed that the effect of applying 12.5 Mg Bs ha-1 was almost similar to that of applying 25 Mg CT ha-1 during the two seasons of study. On the other hand, the application of only 5 Mg Bs ha-1 could improve slightly; but insignificantly some soil characteristics. The combination between “Bs+CT” recorded further significant improvements in the abovementioned characteristics especially at the higher doses of application. Thus, we partially accept the first assumption. To investigate the second one, the availability of N, P, K, Fe, Zn and Mn nutrients was considered in the investigated soil by the end of each growing season in addition to the concentrations of these nutrients within the areal parts of the grown plants. Results obtained herein indicate that biochar underwent considerable decomposition in sandy soils shifting the pH slightly towards alkalinity. . On the other hand, both the biochar and compost could improve significantly the availability of soil macro-and micro- nutrients and hence increased their uptake by the grown plants. These finding does not, therefore, support the second hypothesis. In conclusion, biochar is recommended as a slow release fertilizer for macro- and micro- nutrients when applied at only a half dose of compost and its effect on soil physical and chemical characteristics may extend for more than one year after application.

Field experiments were performed during two summer successive seasons of 2017 and 2018, at a private farm in El- Salhia El-Gedida area, El- Sharqia Governorate, Egypt, to determine the best treatment of sandy soil injection with different rates, from clay and humic acids additive through different doses. In addition to study the effect injected sandy soil by clay and humic acids (IS), different irrigation water levels (IR=100, 90, 80, 70, 60, 50 and 40% calculated based on crop evapotranspiration) and three mineral fertilizer rates (MFR=100, 70 and 40% of recommended chemical fertilizer N, P, K rates) on the marketable yield (MY), crop quality parameters, seasonal actual evapotranspiration (ETa), water use efficacy (WUE) and irrigation water use efficiency (IWUE) for summer cucumber fruits "Cucumis sativus" were investigated. The results reported that; 1) the marketable yield and studied quality parameters except total soluble solid (TSS) and vitamin C (VC) of summer cucumber fruits gave the highest values under IS, IR and MFR =100% treatments for both seasons. 2) Seasonal ETa gave the lowest values: 155.01 and 142.23 mm for both seasons, respectively, under IS, IR and MFR= 40% treatments. 3) The maximum values of summer cucumber fruits WUE and IWUE were 22.03 and 16.63 kg/m3; 26.34 and 18.12 kg/m3 for both seasons, respectively, under IS, IR=60% and MFR=70% treatment. This study concluded that the cultivation of summer cucumber under IS, IR= 60% and MFR= 70% treatment can possibly save about 40% of the applied irrigation water, save about 30% of the total mineral fertilizers rates additive and increased marketable yield of the summer cucumber fruit about 27 and 36% for both seasons, respectively, compared with that under the control treatment (UIS, IR=100% and MFR=100%).

There are many factors playing major role in use efficiency of phosphatic fertilizers, which varies from soil to another. Therefore, this study aims mainly to evaluate the effect of some trails i.e. compost additives and P application times in different methods in sandy soil as well as its effect on growth, productivity and quality of peanut (Arachis hypogaea L.). This study was carried out as field experiment in sandy soil at South Al-Tahrir Sector, Al-Behaira Governorate, Egypt during two successive growing summer seasons. The experiment was laid out in a split plot design with three replicates. Four rates of compost i.e. (C1) 0, (C2) 4.76 (C3) 9.52 and (C4) 14.28 ton ha-1 were arranged in the main plots, while the four treatments of phosphorus were randomly distributed in the sub plots.<br />With all the studied treatments of compost and P, the studied growth parameters i.e. plant height (cm), number of branches per plant, and dry matter weights of straw and leaves were higher in the second growth season than those of first one. Data obtained from our experiments showed that growth parameters increased significantly with the increasing rates of compost application as well as with P applications in three doses (P4). Foliar application of P at 70-80 days of planting (P3) resulted in more increases in the determined growth parameters than those found with other treatments. Similar effect was found with peanut yields of pods and seeds and seeds contents of N, P and K as well as its content of protein and oil.

<br />A laboratory experiment was conducted to study the effect of filter cake and vinasse on copper and nickel adsorption on a loamy sand soil. To attain this aim, five grams of the soil were placed with 0.5 g of filter cake or vinasse in conical flasks. Then, 10 ml of Cu or Ni solutions containing 44 mg Cu or Ni / 10 ml prepared from CuSO4 5H2O and NiSO4. 6H2O, respectively, plus 25 ml of distilled water were added to the flasks to give the initial concentration of Cu or Ni of 1257 mg L-1. Two control flasks of the soil plus Cu or Ni and the soil with distilled water were used. The treatments were repeated three times.<br />The soil suspensions in the flasks were shaken at 25 ° C for five shaking periods of 5, 10, 20, 40 and 60 minutes. The results obtained showed that organic materials resulted in increased efficiency the sorption of Cu and Ni on a loamy sand soil compared to control treatment (without organic materials), and the filter cake was more able to absorb both Cu and Ni compared with vinasse with increased shaking intervals. The highest adsorption amount was 8.53 mg g-1 for copper with the non-amended soil at reaction time 60 minute and 4.72 mg g-1 for nickel with filter cake + soil treatment at reaction time 20 minute. The results also showed that the Freundlich equation for Cu and Ni absorption was better than the Langmuir equation due to that Langmuir equation is unsuitable of adsorption equations with high concentrations of heavy metals under study.

Accurate estimation for groundwater recharge is required for more sustainable management to water resources. On-farm level, deep percolation is one of the water loss sources that researchers and agronomists work hard to minimize. However, on a large scale or district level, it is considered as a valuable source for recharging the aquifer. Indirect estimation to deep percolation would be an economic effective mean, especially for large scale studies. The presented research study aims at checking the capability of Land Information System (LIS) model in estimating deep percolation by soil-water balance equation. The model was validated using precipitation data extracted from meteorological stations randomly selected and distributed along the Nile basin. Multi-thematic map layers including all soil water balance model parameters i.e. deep percolation and change in soil moisture content were developed to the year 2013 at a scale of 10 km2. The relationship between measured rainfall values and estimated ones by LIS has a coefficient of determination (R2) of 0.88. The obtained results revealed a good capacity of LIS model in estimating deep percolation on a large scale from its direct simulation to the soil-water balance parameters. It was found that deep percolation rates were generally higher in the Nile River's downstream than in upstream especially in Egypt, Sudan, and parts of Uganda. This is in contrary to the behavior of precipitation rates and both surface and sub-surface runoff. They were higher in upstream countries than in downstream ones. The highest deep percolation rate (19.63 mm day-1) was observed in Ethiopia and parts of Sudan during May 2013. It was found that low elevated lands with loose texture tend to have higher rates of deep percolation than elevated rocky lands. The current research results could be of great benefit for sustainable water management in Egypt. However, further study should be conducted in different agro-ecological zones in Egypt for more precise model calibration and validation. This may require access to a large amount of field data and long-term meteorological data to run the model.

The study objectives were to use vegetation indices techniques for detecting the change of vegetation cover during three periods: from 1984 to 2001, 2001 to 2018, and 1984 to 2018 and to identify the impact of land capability on land cover changes at Wadi El-Natrun Depression, Egypt. Landsat-8 satellite images dated to 1984, 2001 and 2018 were used to detect the changes in land cover in the investigated area (573.53 km2). Four vegetation indices, including normalized difference vegetation index (NDVI), soil adjusted vegetation index (SAVI), green normalized difference vegetation index (GNDVI) and optimized soil adjusted vegetation index (OSAVI) were used to identify and detect vegetation changes during the last 34 years. Ground truth points were collected in 2018 to test the accuracy of classified images. Forty five soil profiles were examined to represent different geomorphic units created using a digital elevation model (DEM) and Landsat-8 image. Modified Storie index was used to carry out land capability evaluation of the investigated soils. Results showed that the vegetation indices determined land cover classes with high over all accuracy (< 92 %) and a kappa coefficient greater than 0.9. The soils belonged to grades 2, 3, 4 and 5, representing 0.7, 17.88, 75.15 and 2.09 % of the total area respectively. The low land capability is due to excess of soil salinity, coarse soil texture, shallow soil depth, and poor drainage conditions in addition to the results illustrated that there was a positive correlation between the land capability and extension in vegetation land cover.

Evaluation of soil fertility is an important factor for proper decisions making and strategies to achieve more sustainable agricultural systems. The main objective of this research was to evaluate the soil fertility status using ASLE program, GIS techniques and nutrient index in some soils of Dakahlia Governorate. For this purpose, 15 soil samples were randomly distributed within the studied area at a depth of 0-30 cm. Those were subjected to physiochemical analyses in order to evaluate soil fertility properties and nutrient index using Applied System for Land Evaluation (ASLE) software. Data outputs of the studied area were classified into two classes: (i) Good-C2 and (ii) Fair-C3 according to fertility index. Meanwhile, soil rating chart of fertility status was low based on the in their available P, medium in salt index and available K and high in organic carbon and available N according to nutrient index values. The obtained data of this study, therefore, provide insights regarding the potential modeling of soil characteristics data to make the proper decisions for soil fertility management.
