Abstract:
The integrated use of organic and mineral fertilizers is a practical and good way to preserve and sustain soil fertility, which results in increased availability of nutrients in the soil and their absorption by plants, thus increasing crop productivity. Due to the fixation of potassium in the soil, it is necessary to work to increase the vitality of agricultural soil by adding fertilizers. Organic potassium is an important means of increasing the availability of macro- and micro-nutrients.

In Mediterranean-type climates, topsoil frequently dries out during spring. Problems associated with reduced nutrient (P, K) availability in dry topsoil may be overcome by placing fertilisers deeper in the soil, where the soil is more likely to remain moist for longer periods as opposed to conventional fertiliser placement. Deep-P placement has resulted in significant yield improvements for lupin crops in Mediterranean environments because lupin crops generally require soil P supply during spring (throughout the flowering stage); in contrast, wheat yields have seldom improved with deep P place

Abstract:
Chemical fertilizers are a quick way to increase nutrients in the soil, but their use is economically costly and dangerous for the environment. Plant Growth Promoting Bacteria (PGPB) are able to increase the bioavailability of fertilizers through biological nitrogen (N) fixation, as well as potassium (K), phosphorus (P), and zinc (Zn) solubilization. The enhanced amount of soluble macro- and microelements in the close proximity of soil-root interface increases the fertilizer use efficiency ~ by 20-40 %.

Abstract:
The article presents the results of scientific research on the effect of long-term use of mineral fertilizers on the fertility of leached chernozem. Over 25 years of direct action of phosphorus fertilizers in leached chernozem, the content of available phosphorus on fertilized soils at the beginning of the experiment increased from 67 mg/kg to 200 mg/kg against the background of the maximum dose of phosphorus fertilizers (P3). Over the next 25 years of the aftereffect of phosphorus fertilizers, as a result of the removal of nutrients by crop harvests, the content of phosphorus and potassium in

Abstract:
During the field experiment, the effect of potash fertilizers on the yield and quality indicators of the green mass of millet was studied. It was found that the highest yield of green mass (13.4 t/ha) and grain bearing (12.3 t/ha) on average over three years of research was provided by a dose of potassium fertilizer 240 kg/ha. The maximum volume of crude protein (0.27 t/ha), dry matter (3.1 t/ha) and metabolic energy (26.3 GJ/ha) were also obtained with the addition of K240. The specific activity of 137Cs in the products obtained in the experiment did not exceed the sanitary and hygienic stand

Abstract:
The long term goal of this research project was to improve control efficiency of Alternaria diseases while reducing fungicide use, by integration of chemical and non-chemical factors. Non-chemical factors were genotype resistance, age-related resistance and fertilizers. The Specific objectives were: 1) To quantify changes in resistance among genotypes and over time in terms of disease development and specific phases of the disease cycle; 2) To quantify the effects of fertilizers applied to the foliage alone, or in combination with a fungicide, on disease development; 3) To quantify the relativ
