Studies of soil Cd and Zn are often performed on sites that contaminated or have deficient conditions. Soil characteristics crop management could impact the mobility uptake Zn, even when considering unpolluted soils adequate levels. The concentrations these two metals were assessed in silage maize under five P fertilization treatments at growth stages low sufficient Pearson correlation coeffici...

Fertilization of soybean with zinc (Zn) had received considerable attention in recent years due to world-wide spread its deficiency soils and also malnutrition infants children’s. Soybean is high nutrient exhausting crop but sensitive soil. Application Zn fertilizers could be a viable option fulfil this promote yield growth parameters. This experiment was conducted at Jawaharlal Nehru Krishi Vi...

Silicon fertilizer and biochar have been widely used to remediate soil contaminated by heavy metals. The effects mechanism of silicon addition on the metal availability, biological properties, microbial community characteristics need further study in soils Therefore, this research determined how fertilizer, biochar, their combined using affected communities related with nitrogen phosphorus cycl...

A variable rate fertilizer system was developed for control of fertilizer amount by optical sensor measured NDVI of crop. The paper analyzes the input and output conditions of control system, and designed hardware, algorithm and control of fertilizer, mainly software flow and a feedback control way. In the paper, the variable-rate control system consisted of 6 optical sensors mounted on a boom ...

The use of liquid organic fertilizer made from livestock manure is an attempt to provide tomato plants with P and Zn nutrients. This research aimed assess the availability Zn, best growth, yield using based on animal manure. A completely randomized design a two-factor treatment was used set up this study. first aspect three different kinds livestock-based fertilizers—chicken, goat, cow dung. se...

The Gascogne region (SW of France) is cultivated for more than 75% of the area. 83 samples of stream bed sediments were collected in three main Gascogne river basins (Gers, Save and Touch, left tributaries of the Garonne river) to evaluate the impact of agricultural practices on trace elements behavior. Eight potential harmful elements (PHE) (Cr, Co, Ni, Cu, Zn, As, Cd and Pb), four reference e...

Precision agriculture is the developing trend of modern agriculture, and the rational utilization of fertilizer is one of the key technologies in the precision agriculture, which needs to fertilize variably according to the crop needs and soil fertility conditions. Thus a fertilizer automated proportioning equipment is developed to Proportion the three fertilizers: Nitrogen fertilizer, Phosphor...

Just after transplanting, the vegetable has difficulty in nutrients uptake. To explore the effect of different fertilization on spring cabbage (Brassica oleracea L. var. capitata) production and fertilizer use efficiencies, this experiment consisting of six treatments was implemented and divided into three groups: 1) no fertilizer (NF) and vegetable planting fertilizer (VPF); 2) conventional fe...

The inherent problems associated with inorganic fertilizer such as scarcity and high cost informed the invention of cocoa pod husk based organic fertilizer. The impact of the fertilizer on cocoa output is hereby investigated in this study. The study was conducted in Cross-River State, Nigeria and purposive random sampling technique was used to select fifty cocoa farmers including the user and n...

Soil physicochemical properties, soil microbial biomass and bacterial community structures in a rice-wheat cropping system subjected to different fertilizer regimes were investigated in two seasons (June and October). All fertilizer regimes increased the soil microbial biomass carbon and nitrogen. Both fertilizer regime and time had a significant effect on soil physicochemical properties and ba...
