Use of different organic fertilizers on soil fertility improvement, growth and head yield parameters of cabbage (Brassica oleraceae L)

The article presents the results of comparative evaluation of the efficiency of the long-term application of mineral and organic fertilizers in the crop rotation system. It was found that the application of the mineral fertilizer system increased the value of hydrolytic acidity of the soil from 4,30 to 5,29 mg-eq per 100 g of soil, the indicator of metabolic acidity decreased from 5,2 to 4,9 pH units. By the end of the 11th rotation for both fertilizer systems, the content of mobile phosphorus increased by more than 4 times relative to the initial value, its mobility indicator – by 2,2-3,2 times compared with the control. The use of the organo-mineral system was accompanied by an increase in the content of humus by 0,35 % and a decrease in the C:N ratio from 11,2 to 8,9. The increased productivity of wheat was revealed when applying nitrogen and nitrogen-phosphorus fertilizers against the background of prolonged use of the mineral and organo-mineral fertilizer system. The change in wheat productivity by 56 % depended on the content of mineral nitrogen, mobile phosphorus, humus in the topsoil, and on the phosphate ion mobility. Soybean productivity depended on soil fertility indicators only by 24 %: the relationship between soybean productivity and the mineral forms of nitrogen and phosphorus is weak and direct, between productivity and P2O5 mobility - weak and inverse, with humus - moderate and direct.

Soil Fertility Improvement

Excess use of agrochemicals for intensive cultivation affects crop quality and destroys agro-ecosystems, and eventually creates health hazards. The study aims to investigate the effect of Gliricidia sepium (GS) tree leaf as suitable green manures for supplementing nutrient supply along with nitrogen (N) fertilizer to produce quality tomato and soil fertility improvement. A field experiment was conducted at the Bangabandhu Sheikh Mujibur Rahman Agricultural University, Bangladesh, from November 2016 to March 2017. The experiment was laid out in a randomized complete block design (two factors) with three replications. There were nine treatment combinations with three levels of GS tree leaves (5, 10 and 15 t ha−1) and three doses of N (0, 50 and 100% of the recommended dose of fertilizer). The highest tomato yield was recorded in GS15×N100 treatment combination, which was 41.68% higher compared to the control treatment. Decreasing C: N ratio in increasing dose of GS and N treated plot indicated the quality of tree leaves that ensures faster decomposition and high nutrient release pattern of this species. Increasing rate of soil pH and cation exchange capacity (CEC) in different treatments as compared to initial soil showed soil fertility improvement. Overall, the results indicated that quality tomato could be grown successfully by the application of G. sepium tree leaves along with an appropriate amount of N fertilizer. Ann. Bangladesh Agric.

Pollution of the environment with waste is the basis of the degradation of the natural system. To prevent this, it is necessary to protect natural resources as much as possible and organize the recycling of waste. Azerbaijan has sufficient resources to prepare organic fertilizers based on new technologies. The presented article discusses the damage caused to the environment by pollution of lands of Neftchala region. The need for agro-technical measures to restore such areas that have lost their fertility is emphasized. In landscaping research, it is recommended to grow soybeans on such lands and apply high doses of organic fertilizers to ensure their normal development.

Plant Life

A growing plant obtains energy from the sun's rays and fertility from the soil and transforms these raw materials into wholesome food for man and beast. Without plant food we cannot have plant life. . Withdrawals of soil fertility must be replenished. Farm animal manures, plant refuse, meat works manures and chemical fertilizers constitute the principal means used to offset these losses.
