In many parts of the world food security is at risk. One of the biophysical root causes of falling per-capita food production is the declining quality and quantity of soils. To reverse this trend and increase soil fertility soil and plant nutrients have to be replenished. This review provides a literature survey of experiences of using multi-nutrient rock fertilizers for soil fertility enhancem...

The widespread application of fertilizers has greatly influenced many processes and properties of agroecosystems, and agricultural fertilization is expected to increase even further in the future. To date, most research on fertilizer impacts has used short-term studies, which may be unrepresentative of long-term responses, thus hindering our capacity to predict long-term impacts. Here, we exami...

An inductively coupled plasma atomic emission spectrometry (ICP-AES) method was developed for the determination of phosphorus in fertilizers. Total phosphorus, direct extraction available phosphorus (EDTA), and water-soluble phosphorus, reported as phosphorus pentoxide (P205), in 15 Magruder check fertilizers were measured by ICP-AES, and the results were compared with those obtained by the AOA...

Abstract Late blight disease is one of the problems faced by potato farmers. Chemical fertilizer and biological (bio-fertilizer) reported have a potential to control late disease. However, there lack research on effect combining use different types bio-fertilizers with doses chemical fertilizers in plants This study aims analyze plants. was conducted from June August Sembalun District, West Nus...

Fertilizer regimes have profound effects on crop yield, soil fertility, and microbial community structure. However, the impacts of partially substituting mineral nitrogen (N) with organic N and/or controlled-release combining micronutrient fertilizers properties communities are still unclear in double-rice systems. The objective this study was to compare rice nutrient condition, bacterial alpha...

This paper presents the most important issues relating to the infl uence of mineral fertilizers on both the natural environment and human and animal health. The physiological, environmental and economic impact of fertilizer production and application, resulted from a low assimilation of mineral components by crops, has been described. The research on the development and production of a large an...
