Continual application of mineral fertilizer and manures to meet crop production goals has resulted in the buildup of soil P concentrations in many areas. A rainfall simulation study was conducted to evaluate the effect of the application of P sources differing in water-soluble P (WSP) concentration on P transport in runoff from two grassed and one no-till soil (2 m(2) plots). Triple superphosph...

The thermochemical transformation of sewage sludge (SS) to biochar (SSB) allows exploring the advantages SS and reduces possible environmental risks associated with its use. Recent studies have shown that SSB is nutrient-rich may replace mineral fertilizers. However, there are still some questions be answered about residual effect on soil nutrient availability. In addition, most previous were c...

Cadmium (Cd) ) may accumulate in soils which have been regularly fertilized with phosphate fertilizers which contain Cd originating in rock phosphate. Soil was taken from three sites in the wheatbelt of Western Australia which were estimated to have received different amounts of phosphate fertilizer over the past decade. The pH was adjusted with dilute HCl or CaC03. No Cd was added experimental...

Rock phosphate (RP) addition in cow-dung waste-paper mixtures at rates above 2% P has been reported to increase the rate of bio-transformation and humification of organic waste mixtures during vermicomposting to produce organic fertilizer for organic farming. However, the optimization of RP for vermicomposting was not established. The objective of this study was to determine the optimal amount ...

The combination of Biotara bio fertilizer and dolomite is known to improve the potential acid sulphate soil fertility. This research has been carried out examine effect as fertilizer, chicken manure, on several chemical properties soybean growth in from May 2018 January 2019 at greenhouse Agricultural Faculty, Universitas Sumatera Utara Medan. using factorial randomized block design with 2 (two...

Phosphorus (P) deficiency is a major constraint to crop production on highly weathered, lowactivity clay soils in the humid zone of West Africa. Past research suggested a linear relationship between grain yield and P uptake over a range of fertilizer P applied to upland rice cultivars. However, there is lack of information on how these relationships are affected by the long-term fertilizer ...

Increasing fertilizer consumption has led to low fertilizer use efficiency and environmental problems. Identifying nutrient-efficient genes will facilitate the breeding of crops with improved fertilizer use efficiency. This research performed a genome-wide sequence analysis of the A (NFYA), B (NFYB), and C (NFYC) subunits of Nuclear Factor Y (NF-Y) in wheat (Triticum aestivum) and further inves...

Human urine constitutes 1% of domestic wastewater and can be used to recover nitrogen phosphorus when collected separately at source. Sustainable nutrient (nitrogen, phosphate, potassium) cycling requires the recovery these valuable resources from human urine. As are nutrients needed for plant growth, components an excellent fertilizer. Phosphorus applied in natural fertilizers addition polluti...

his paper seeks to understand the influence of different levels of fertilizer nutrients on annual yield of cardamom in cardamom hill reserves (chr) under rain fed situation. field experiment conducted at crs, pampadumpara during 1994-2002 on nutrient levels with sources revealed that increasing the levels of nitrogen, phosphorus and potassium had increased the yields of cardamom up to 125: 125:...

This study aims to obtain the formulation of Mono Potassium Phosphate (MKP) fertilizer and fermented rabbit solid manure at most appropriate dose for growth production chili plants. research is a factorial experiment with randomized block design (RAK) 2 factors being tried. In first factor, MKP consists 3 levels: M 1 = g.l-1 water, 4 6 water,. The second factor P 10 tons ha-1, 20 30 ha-1. inter...
