Effect of new specific fertilizer on the growth of peanut

Based on the soil nutrient condition of Fujian province and the nutritional characteristic of peanut, new specific peanut fertilizer was made with some new types of synergists and chemical fertilizers. In 2005, a field experiment was conducted to study the effect of the new specific fertilizer on peanut at Gaobi town, Longyan city, Fujian province. The results showed that, the new specific fertilizer could relieve the inhibition of fertilizers on nodule formation of peanut, promote the growth of peanut plants, increase the yield of peanut and improve the utilization rate of fertilizer, contrasted to common fertilizers. To compare with one time application of common fertilizers, the new specific fertilizer which was applied one time and twice had significant positive influences on yield of peanut and nutrient use efficiency, increased economic yield of peanut by 3.8% and 6.3%; improved nitrogen, phosphorus and potassium use efficiency by 3.9, 2.8, 4.3 and 4.5, 5.7, 7.4 percentage points respectively. Compared with twice applications of common fertilizers, the new specific fertilizer which was applied as the method above increased economic yield of peanut by 0.7% and 3.2%; improved nitrogen, phosphorus and potassium use efficiency by 0.3, 1.6, 0.5 and 0.9 4.5, 3.6 percentage points respectively.

Green intelligent fertilizers——A novel approach for aligning sustainable agriculture with green development

This review addresses the growing disparity between the current state of fertilizer production in China and the evolving demands of green agriculture in the 21st century. It explores major advances in fertilizers, proposes the concept of green intelligent fertilizers and develops new strategies aligned with the principles of green development in fertilizer industry and agriculture.Green intelligent fertilizers may be designed to maximize the synergistic effects among plants, soils, microorganisms, nutrient sources and the environment. This concept emphasizes the integration of industry and agriculture toward green development for entire industry chain, using an interdisciplinary approach to drive the green transformation of fertilizer industry, and promote green and sustainable development of agriculture. By bridging the gap between the current state of fertilizer industry and a growing need for environmentally responsible agricultural practices, this review highlights a path toward harmonizing fertilizer production with the imperatives of green agriculture.

Organomineral Phosphorus Fertilization in the Production of Corn,Soybean and Bean Cultivated in Succession

The use of organic waste in agriculture has been used aiming at greater productivity, decrease in the cost of production and sustainable use of resources. The present study aimed at evaluating the effect of phosphate fertilization with the maintenance of organomineral fertilizers, combining poultry manure and soluble or reactive phosphate, in the production of grains in corn culture and the residual effect for subsequent crops of beans and soybeans. The experiment was conducted in Sete Lagoas, MG, in 2015, using three fertilizers with sources of different phosphorus sources (triple super phosphate—STP, organomineral with STP and organomineral with Bayovar phosphate) applied at the doses of 65, 130, 195 and 260 kg·ha¯1 of P2O5 total, and compared to the control without phosphate fertilization. We evaluated the contents of foliar P, P accumulation in the grains, yields of corn grains, beans and soy, accumulated productivity and export of accumulated P of the three cultures. The three cultures assessed presented higher productivity when compared to the average of the factorial treatments that received phosphate fertilization relative to the control. Organomineral fertilizers increased grain production, obtaining average productivity equal to or greater than those obtained with the exclusive use of STP.
