Soil Losses

The most important problem in the highland area is the development of technologies to reduce water erosion and improve soil fertility preservation. In order to restore degraded soils of slope lands, a number of measure is undertaken, among them planting crops across the slope and rational fertilizer treatment. To reduce erosion processes, mineral fertilizers were applied depending on the steepness of slope. High sections with the steepness of 9–10∘ received ammonium sulphate in a quantity of 60 kg/ha. Lower part of the slope with the steepness of 5–7∘ received ammonia nitrate as a nitrogen fertilizer in a quantity of 80 kg/ha, while the gentle sloping part with 2–5∘ had urea-formaldehyde fertilizer incorporated under winter tillage in a quantity of 50 kg/ha. At that, stripes were formed across the slope where tall-growing perennial herbs were planted: hill mustard (Bunias orentalis L.), silphium (Silphium perfaliatum), Eastern galega (Galeqa orientalis L.), cock’s foot grass (Dakfilis qlamerata L.). The research results have shown that thanks to fertilizers, yield of crops increases by a factor of 1.5–2, while soil losses reduced from 0.042 to 0.018 t/ha.

Ultimate Purpose

The study deals with the combination of biopolymers to develop hydrogels intended for agriculture application. The aim is to propose a renewable and eco-compatible solution to enhance agrochemicals and water efficiency and contribute to maintaining soil fertility. We developed a set of hydrogels based on casein and chitosan for water retention and release of agrochemicals, in particular nitrogen fertilizer urea. The weight ratio of biopolymers, from 0.5 to 2, was investigated to understand the influence of their content on the morphology, swelling, swelling-drying cycles, and water retention in soil. The average content of urea in the hydrogels was 30% of the total weight, and up to 80% was released in the soil in 50 days. The biodegradation of the hydrogels in soil has been investigated by the burial method and monitoring the release of CO2. Results demonstrated that by increasing the content of chitosan, the biodegradation time is prolonged up to 20% in 90 days. The obtained results support the ultimate purpose of the work that the combination of two biopolymers at proper weight ratio could be a valid alternative of the marketed hydrogels with the final goal to promote soil fertility and water retention and prolong biodegradation.

Native Strain

One of the ways to maintain soil fertility is to use organic fertilizers. One of them can be straw of cereal crops (winter wheat and barley). However, the process of its decomposition can be delayed for several years. It is possible to accelerate the transformation process by using the native strain of cellulosolytic micromycete (Humicola fuscoatra VNIISS 016). Its introduction together with straw before plowing stabilizes agrophytocenosis. The experiments were carried out in laboratory under simulated conditions close to field ones. Scheme of the experiment: 1. Straw; 2. Straw + N (40 mg/4 g, which corresponds to 40 kg/ha); 3. Straw + N + H. fuscoatra + PC (nutritional supplement – molasses) (Kolesnikova M.V., 2014). As a result of the studies, it was established that winter wheat straw without additional components lost 0.86 g in weight (from the initial 4 g), 1.03 g when adding nitrogen fertilizer to the straw, and 1.49 g when using H. fuscoatra. We found that the addition of nitrogen to the straw stimulate the process of its transformation. Straw with nitrogen decompose faster than straw without any additives (by 41.5%). However, the addition of the native strain of micromycete accelerate the process by 48.3%. Barley straw lost 0.82 g in weight, straw with nitrogen fertilizer lost 1.06 g, straw and H. fuscoatra – 1.13 g. Further, the decomposition rate increased in the following row: straw → straw + N, where the speed was 26.7% higher → straw + N + H. fuscoatra, the decomposition rate is – 85.3% higher.

Aims: To evaluate the possibility of allelopathic effects of the rotated crops on productivity, chemical composition, N utilization of wheat and soil fertility. Study Design: A split plot design with three replications was used. The main plots were assigned with three previous crops, The sub plots were assigned by three nitrogen fertilizer rates (0, 35 and 70 kg N fed-1). Place and Duration of Study: A field study was carried out at Sakha Agricultural Research Station farm, ARC, Kafr El-Sheikh governorate, Egypt, during two successive seasons of 2016/2017and 2017/2018 Methodology: The local wheat cultivar (Sids 12) was sown after three crops (fahl berseem) after rice, (Drawa) after rice and Fallow after rice as preceded crops. Results: The results showed that fahl berseem roots and residues in the clover (berseem)-wheat rotation secreted biologically active chemical compounds which have a positive effect on growth and development of wheat. The preceding clover (fahl berseem) wheat rotation appeared to be promising for wheat productivity, N, P, K concentrations, N-uptake, N utilization, protein content of wheat grain and straw, availability of N, P and K after wheat harvest compared with fallow after rice, green maize (drawa-wheat rotation). The interaction between the preceded crops and N fertilizer rates was significantly for all the studied traits. The highest performance of wheat traits were observed when wheat was grown after fahl berseem and fertilized with 70 kg N.fed-1. While the lowest performance was obtained following cereal crops rice (fallow) and the lowest N level in both seasons. Treatment of fahl berseem with nitrogen fertilizer (70 kg N.fed-1) had given a best values from grain yield with relative increments of (37.54%) compared with preceding rice-wheat rotation and (23.26%) compared with rice-drawa rotation. Conclusions: Cereal winter crops can be sow after preceding legume crops rather than summer cereal crops. We can sow fahl berseem crop as a forage to animals after cereal crop (rice) and before sowing wheat crop to improve soil properties and its availability of the essential elements and consider additional revenue to farmer. Fahl barseem had be sown in the end of august month after rice crop to produce approximetly 20 ton fresh forage.fed-1 (~ 9 ton dry grass.fed-1) which provides farmers with (~ 9 thousands EL) in 88 days only.
