Research ArticleOpen accessEvery word in the titlePhosphorus Availability Modulates Bradyrhizobium japonicum’s Impact on Soil Micribial Biomass and Soybean (Glycine max (L.) Merrill) Yield in Lubumbashi Tropical SoilsBen Tshibuyi Kasu-Bandi et al.Tropical soils in sub-Saharan Africa exhibit low fertility, high acidity, and limited Phosphorus (P) availability, a key nutrient for agricultural productivity and the sustainability of cropping systems. This deficiency, exacerbated by the strong fixation of P in acidic soils, not only limits plant growth but also the efficiency of the nitrogen-fixing symbiosis between soybeans (Glycine max (L.) Merrill) and Bradyrhizobium … …American Journal of Agricultural and Biological Sciences, Vol. 21, Issue 1 · 13 May 2026 · 1,980 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDynamics of Mobile Phosphorus and Potassium in the Soils of Agricultural Lands of Kostanay RegionAlmabek Nugmanov, Aliya Yskak, Tatiana Paramonova et al.Soil phosphorus deficiency is a growing constraint on crop productivity in the agricultural lands of the Kostanay Region, Republic of Kazakhstan, yet systematic data on the spatial dynamics of mobile phosphorus and potassium across soil types remain limited. This study assessed the availability of mobile forms of phosphorus and potassium, alongside key physicochemical properties, including soil pH and cation exchange … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 14 Apr 2026 · 1,594 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Study on Response of Sugarcane Genotypes to Phosphorus Fertilizer in Western Guangdong, ChinaJin Li, Chao Zheng, Xianmin Wang et al.To optimize Phosphorus (P) fertilization, three sugarcane genotypes(ROC22, LC5135, and YT236) widely cultivated in western Guangdong, China wereused for the experiment in which 5 levels of P fertilizer were set up to studythe effects of their application. The results showed that: (1) P fertilization amountwithin 288 kg/hm2 P2O5 could increase theplant height, stem diameter, and weight and yield of sugarcanes. … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 5 Oct 2022 · 5,628 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNodulation and Biomass Yield Response of Cowpea to Row Spacing and Phosphorus Fertilizer Application in the Guinea Savanna Agro-Ecological Zone of GhanaAlhassan Bawa, Lukman YussifPhosphorus fertilizer application and planting distance play a major role in the production of shoot, root and nodule dry biomass of cowpea. However, phosphorus is a major limiting nutrient in soils in Ghana. Selection of cowpea varieties that produce good biomass yield under low soil phosphorus or those with high phosphorus response efficiency can be a low input approach in … …American Journal of Agricultural and Biological Sciences, Vol. 12, Issue 4 · 23 Jan 2018 · 8,231 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Phosphorus Application and Arbuscular Mycorrhizal Fungi Inoculation on the Growth of American Jointvetch and Greenleaf DesmodiumManabu Tobisa, Yoshinori UchidaThis study examined the growth and Arbuscular Mycorrhizal (AM) colonization of two tropical forage legumes, namely, American jointvetch (Aj) and Greenleaf desmodium (Gd), at two phosphate application rates (0 or 10 g P m-2 yr-1; -P or +P), with or without AM (+AM or -AM) in a pot experiment. AM inoculation and P application promoted the growth of both species. … …American Journal of Agricultural and Biological Sciences, Vol. 12, Issue 2 · 9 Jun 2017 · 8,148 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThermodynamics, Non-Linear Isotherms, Statistical Modeling and Optimization of Phosphorus Adsorption from WastewaterAkinpelu Kamoru BabayemiPalm Kernel Shell (PKN), an eco-friendly biomass, was carbonized and activated for the removal of phosphorus from wastewater through batch adsorption process. The studies evaluate the effects of pH, particle size, dosage and contact time on the adsorption capacity of the prepared adsorbent. The equilibrium concentration data and the amount of adsorption were described using non-linear regression analysis of the … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 19 Nov 2016 · 7,512 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUsing Bioethanol Wastes as an Alternative Phosphorus Source for Snap Bean and Radish ProductionXiaolin Liao, Ben Hogue, Shouliang Zhu et al.Biorefinery waste has potential to provide alternative sources of phosphorus (P) for plant industry if biomass has been pretreated by phosphoric acids during its production process. In this study, we investigated the potential of the fermentation waste from a bioethanol process as a P fertilizer. Three treatments were set up for growing crops of snap bean (var., Bronco) and radish … …American Journal of Environmental Sciences, Vol. 12, Issue 1 · 4 Feb 2016 · 8,144 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIMPROVING PHOSPHORUS NUTRITION OF COTTONWalter B. Gordon, Larry Murphy, Pawel WiatrakCrop recovery of applied Phosphorus (P) fertilizer can be low, especially during season of low soil temperature, which decreases plant root growth and nutrient uptake. The H2PO4- or HPO4-2 anions readily react with soil cations such as Calcium (Ca), Magnesium (Mg), iron (Fe) and Aluminum (Al) to produce various phosphate compounds of very limited water solubility. Specialty Fertilizer Products (SFP), … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 10 May 2014 · 7,110 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIMPROVING PHOSPHORUS NUTRITION OF CORNWalter B. Gordon, Larry Murphy, Pawel WiatrakPhosphorus (P) generally occurs in soils as the anions H2PO4- or HPO4-2 depending on soil pH. These anions readily react with soil cations such as calcium, magnesium, iron and aluminum to produce various phosphate compounds of very limited water solubility. Crop recovery of applied phosphate fertilizer can be quite low during the season of application. In addition, the large amounts … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 18 Mar 2014 · 7,446 accessesView PDFCite
