Increasing the use of organic fertilizers is an effective measure to improve, increase soil fertility and maintain crop yields. The aim of this study was to investigate the influence of different types of organic fertilizers on the early yield of grapes and soil parameters, as well as the relationship between soil parameters and grape yield under fertilization conditions. The ‘Shine Muscat’ grape was used as the material, with early maturing cultivation in the solar greenhouse. From the time of grape planting, three-year continuous fertilization management was carried out using five types of base fertilizers: chemical fertilizer (CK), fermented corn stalk residue (A1), mature sheep manure (A2) and two types of commercial organic fertilizers (B1 and B2). In the third year, berry and soil samples were collected to determine grape yield and evaluate soil physicochemical properties, nutrient status and changes in enzyme activity, studying the relationship between grape yield and soil indicators. The results show that compared to CK, the grape yields with B1 and B2 increased by 19.04% and 16.26%, respectively, while A1 and A2 decreased by 24.09% and 18.97%. Organic fertilizer application reduced soil bulk density, increased soil porosity, enhanced soil organic matter content and effectively buffered soil pH levels. Two types of commercial fertilizers (B1 and B2) improved soil total nitrogen, total phosphorus, total potassium, available nitrogen and available phosphorus content to varying degrees. All organic fertilizer treatments effectively increased soil enzyme activity, except for soil sucrase activity. Through correlation and regression analyses, it was found that in this study, the levels of available nitrogen, available potassium and soil saccharase activity were most closely related to early grape yield. Their influence on grape yield was in the order of available nitrogen > soil saccharase activity > available potassium. Therefore, with a combined organic and inorganic basal fertilization system, the fertilizer nutrients are more comprehensive and help to increase the productivity of grapes at the beginning of the fruiting period. Nitrogen and phosphorus are very important in the maintaining of grape yields and improving sucrose activity in the soil through the application of organic fertilizers cannot be ignored when increasing yields.

“…The primary measures for the development of organic farming here may be the production of organic corn due to its minimum transpiration coefficient (300) among all cultivated cereals and the insignificant response of the crop to soil fertility. Production experiments in the Almaty region showed an almost 50% increase in the corn harvest when using organic fertilizers [87]. In addition, to saturate the domestic market, it is advisable to produce organic vegetables on irrigated lands, potatoes, sweet peppers, onions and garlic, especially the last two crops actively used in the manufacture of Kazakh national dishes, beshparmak and horse sausages (kazy and shuzhuk), respectively.…”

In the context of the transition to sustainable agriculture in Kazakhstan, the article considers one of its forms—organic farming. The adopted laws and by-laws not only have not contributed to but have also significantly hindered the development of organic farming due to the complexity of their implementation in the Kazakh legal field. The activities of Kazakhstani public organizations, deprived of any state support, are symbolic in nature. The absolute instability of organic production, the multidirectional long-term dynamics of the area of organic land and the cost yield of the products are demonstrated. The lack of demand for organic farming products among the population of Kazakhstan is due to socio-economic determinants, the dominance of livestock products in the nutrition structure of the indigenous population, only a small part of the inhabitants of megacities being the main consumers of any organic products, the exorbitant share of food costs and the high premium of organic products. The reasons for the ecological and economic instability of organic farming are the extensive development model, the lack of subsidiary obligations of the state and the zero-marginal cost of the export product. Conservative, utilitarian and innovative ways of developing organic farming are proposed.

“…Biologically active compounds released by organic fertilisers have a positive effect on yield and quality indicators, such as fatty acids, vitamins, amino acids, and polypeptides [17]. Organic fertilisers can have an effect on oil content and composition through changes in the availability of nutrients to plants [18].…”

Organic waste can provide an alternative to synthetic fertilisers for maintaining productivity with limited environmental impact. Our research evaluates the potential use of processed animal waste in corn fertilisation, which may represent a partially closed nutrient cycle of importance in a sustainable agricultural system. The objective of this study was to evaluate the quantity and quality of fat obtained from corn grain fertilised with meat and bone meal (MBM) produced from animal waste. A static field experiment using MBM was conducted at the Experimental Station in Tomaszkowo (53°71′ N, 20°43′ E), Poland. The field experiment was conducted in 2014–2017 with continuous corn cultivation. The course of weather conditions in the years of this study influenced the fat content, with the lowest amount found in 2016. The application of fertilisers in the form of MBM and mineral fertilisation resulted in a slightly lower fat content compared to the variant without fertilisation. The application of mineral fertilisers and MBM influenced an increase in the content of the predominant C18:2 acid compared to the variant without fertilisation, while the opposite was shown for C18:1 cis-9 acid. The fertiliser variants are most correlated with fat yield and total polyunsaturated fatty acids. The fertiliser variants in their effects on fat yield, fat content, fatty acid profiles, and their ratios can be divided into three groups, which were related to the effects of organic fertilisers during the years of this study. The use of meat and bone meal as fertilisers cannot be regarded as a factor in increasing the fat content of corn grain. Meat and bone meal applied over several years to the same field in the quantities required to achieve optimum yield can be an element that shapes fatty acid profiles.
