Nutripellet pack is a tubular assembly composed of fertilizer pellet, manure pellet and bioinoculants. A laboratory electrolyte release study was conducted to assess the extent nutrient enrichment by from encapsulated pellet. placed in soil, within closed container. Periodically entire soil removed for estimation reaction (pH), electrical conductivity (EC) available forms N, P K up 11 weeks aft...

High N loss and low N use efficiency (NUE), caused by high N fertilizer inputs and inappropriate fertilization patterns, have become important issues in the rice (Oryza sativa L.) growing regions of southern China. Changing current farmer fertilizer practice (FFP, 225 kg ha-1 N as three applications, 40% as basal fertilizer, 30% as tillering fertilizer and 30% as jointing fertilizer) to one-tim...

Ipomoea batatas, popularly known as sweet potato, is a species of the Convolvulaceae family, with probable origin between Mexico and northern South America. Among genotypes economic potential, biofortified cultivar Beauregard (Ipomoea batatas) stands out due to its rusticity easy handling. Controlled-release fertilizers were mostly used in studies developed other countries, their study being ne...

As the saline-alkali paddy area continues to grow, nutrient (e.g., nitrogen (N) and phosphorus (P)) runoff loss is becoming more serious in world. The N-fertilizer application affects risk paddy. Selecting suitable fertilizer types reduce beneficial agricultural sustainability. However, effects of are not clear. This study measured N P concentration surface water paddy, using various N—fertiliz...

Biochar is a potential solution for addressing environmental problems related to excessive nitrogen (N). However, there still some debate about the absorption and desorption of nitrate (NO3−-N). Therefore, this study investigated NO3−-N adsorption performance onto biochar biochar-soil mixture address gap. The results showed that produced from apple branches had ability absorb with an capacity 3...

15N-labeled fertilizer was applied to Sorghum at different rates (0, 100 kg N.ha -1 ) to 1m2 microplots and with two kind of water (well water “WW” and treated wastewater “TWW”) to Sorghum grown in field during 1997 and 1999. Increases in DM production, N uptake and 15 NRF were observed with TWW. About 17% and 36% of the 15Nfertilizer were recovered in the crop with TWW in 1997 and 1999, respec...

The source and quantity of nutrients available to plants can affect the quality of leafy herbs. A study was conducted to compare quality of Cosmos caudatus in response to rates of organic and mineral-based fertilizers. Organic based fertilizer GOBI (8% N:8% P₂O₅:8% K₂O) and inorganic fertilizer (15% N, 15% P₂O₅, 15% K₂O) were evaluated based on N element rates at 0, 30, 60, 90, 120 kg h⁻¹. Appl...
