Abstract:
ABSTRACT The effects of mineral fertilizer (NPK) and organic manure on the community structure of soil ammonia-oxidizing bacteria (AOB) was investigated in a long-term (16-year) fertilizer experiment. The experiment included seven treatments: organic manure, half organic manure N plus half fertilizer N, fertilizer NPK, fertilizer NP, fertilizer NK, fertilizer PK, and the control (without fertilization). N fertilization greatly increased soil nitrification potential, and mineral N fertilizer had a greater impact than organic manure, while N deficiency treatment (PK) had no significant effect. A

Abstract:
The recent boom in organic business in the name of Mbeya manure fertilizer has taken shape in commercialisation without government approval as several implications were at stake. Laboratory and field experiments were, therefore, conducted to ascertain the quality of the products with and without modifications. The original products, as proclaimed by suppliers, were evaluated against the control treatment of inorganic fertilizer and the modified products by the inclusion of specific microorganisms in solubilisation of fixed nutrients and oxidation of ammonia and nitrite.

Objectives : This study aimed to monitor ammonia volatilization in upland fields under different nitrogen fertilizer applications, comparing compost manure (CM) and composite fertilizer (CF) and investigate the environmental factors influencing ammonia volatilization.Methods : Ammonia was collected using the static chamber method in upland fields, and the soil analyses were conducted before and after ammonia volatilization monitoring. Pearson's correlation analysis and machine learning were utilized to determine the relationship between ammonia volatilization and environmental factors. Growth

Abstract:
Ammoniac saltpeter is the most widespread in the world and effective nitric fertilizer. However, ammonia saltpeter has a severe disadvantage – fire risk and explosion hazard that causes some difficulties and restrictions of both its consumers and its manufacturers. The purpose of the present work consisted in the studying the possibility of production of NPК-fertilizers with improved agrochemical properties and a controlled ratio of nutrients N/Р2О5/К2О produced based on an ammonia saltpeter solution, ground phosphate rock, and potassium chloride.

Abstract:
Nitrogen (N) is an essential plant nutrient, therefore, N-deficient soils affect plant growth and development. The excessive and unwise application of N fertilizers result in nutrient losses and lower nutrient use efficiency that leads to the low crop productivity. Ammonia volatilization causes a major loss after N fertilization that causes environmental pollution. This experiment was conducted to evaluate the effectiveness of coating and uncoating N fertilizer in enhancing yield and nutrient-use efficiency with reduced ammonia emissions.

Background Green manure is an important source of organic fertilizer. Exploring green fertilizer and nitrogen fertilizer reduction is important for agricultural production. However, few studies have been conducted, especially on the effects of different green fertilizers along with reduced nitrogen fertilizer application on soil ammonia volatilization emissions, rice yield, and nitrogen fertilizer uptake and utilization.

Abstract:
The rising shortage of fertilizer resources in crop-producing regions worldwide and the need for fertilizer use optimization to minimize the impact of salt injuries and ammonia toxicity are at the centre of a brewing storm call for sustainable fertilizer savings. The allocation of fertilizers will be an ever-increasing pressure source because of vast agricultural demands under changing climatic conditions. Therefore, starter fertilizers must complement their efficiency and aim to boost productivity and improve food quality to reduce its toxicities, and these observations are corroborated by an

Abstract:
Traditional practices for managing irrigation and fertilizer in Chinese rice fields have historically consumed large amounts of water resources and caused serious gaseous nitrogen losses (ammonia volatilization and N2O), resulting in low water and fertilizer use efficiency. While both water-saving irrigation and substituting organic fertilizer for chemical fertilizer can impact ammonia volatilization and N2O emissions, the impact of their combined application on gaseous nitrogen loss in rice fields remains unclear. To achieve this goal, we conducted a two-year experiment using two irrigation m
