Long-term research shows that phosphorus (P) and nitrogen (N) fertilizer must be applied to optimize production of irrigated grain sorghum in western Kansas. In 2020, N alone increased yields 60 bu/a, whereas P together up 83 bu/a. Averaged across the past 10 years, fertilization 82 The application 160 lb/a (with P) produced maximum yield which is slightly less than 10-year average (2011–2020)....

Highly fractionated granites and related magmatic-hydrothermal ore-forming processes can be traced by elemental ratios such as Nb/Ta, K/Rb, Y/Ho, Sr/Eu, Eu/Eu*, Zr/Hf, Rb/Sr. The lanthanide “tetrad effect” parameter (TE1,3) also a useful geochemical fingerprint of highly granites. This work assesses its application an exploration vector for granite-related mineralization in the Central Iberian ...

Cultivating naturally colored fiber cotton has excellent potential for the Northeast of Brazil. However, its cultivation in semiarid occurs with low use technology and inputs soils phosphorus content. This work evaluated productivity quality cultivars under fertilization Brazilian region. The experimental design was randomized blocks, treatments arranged split plots four replications. five P do...

ABSTRACT A serious problem in fresh corn growing regions is the low availability of phosphorus (P), especially Cerrado (Brazilian Savanna) biome. This study aimed to evaluate performance experimental double hybrids intended natura consumption grown under and high P availability. randomized blocks design was used, a 2 × 21 factorial arrangement, consisting two availabilities (37.5 75 mg dm−3 P2O...

To improve the magnesia removal effect of collophane and increase P2O5 grade phosphorus concentrate, fatty acid collector mixed with sodium dodecyl sulfate (SDS) was used as compound in reverse flotation for system. Solution surface tension measurement, Zeta potential test infrared spectrum analysis were conducted to analyze intensified dolomite removal. The results showed that under conditions...

The experiment was undertaken during Kharif season of 2019, 2020 and 2021 at Regional Research Station, S. D. Agricultural University, Kothara (Gujarat). treatments comprised three levels nitrogen (N1: 10 kg N/ha, N2: 20 N/ha N3: 30 N/ha) phosphorus (P1: 0, P2: 20, P3: 40 P2O5/ha) laid out in a factorial randomized block design with replications. Effect different on Marvel green forage yield fo...

Nitrogen (N) and Phosphorus (P) deficiency is a major yield limiting factor across the globe their proper management plays vital role in optimizing crop yield. This field experiment was conducted to assess impact of soil plant nitrogen N P ratio on growth wheat (Triticum aestivum L.) alkaline calcareous soil. The study consisted various levels (0, 40, 80, 160 kg ha−1 as urea) phosphorus 30, 60,...

In order to achieve the purpose of high-efficiency dephosphorization by single-slag method during combined blown converter steelmaking process, CaO-SiO2-FetO-MgO-MnO-P2O5 slag system was taken as research object, and slag-forming route studied. The effects compositions on liquidus contour map phosphorus distribution ratios (recorded Lp) were calculated thermodynamics software FactSage, then the...

To date, accumulated industrial waste creates serious environmental problems in the regions. Therefore, their processing order to obtain valuable products is an urgent task. As a result of reduction electric smelting phosphorite raw materials Novo-Dzhambul phosphorus plant, about 150-160 kg cuttrel dust formed per 1 ton yellow phosphorus. The resulting considered as secondary material, it can b...

ABSTRACT Family farming is important for the production of food human consumption, but it lacks resources to invest in soil fertility its crops. The objective this study was analyze whether use green manures increases terms nutrients N, P and K with low environmental risk family agricultural production. An experiment set up State Mato Grosso (Brazil), randomized complete block design, a 6 x 3 f...
