Soil phosphorus availability and soybean response to phosphorus starter fertilizer [PDF]
Revista Brasileira de Ciência do Solo, 2014 Phosphorus fixation in tropical soils may decrease under no-till. In this case, P fertilizer could be surface-spread, which would improve farm operations by decreasing the time spend in reloading the planter with fertilizers. In the long term, less soluble P sources could be viable.

Phosphorus Balance and Soil Phosphorus Status in Paddy Rice Fields with Various Fertilizer Practices
Plant Production Science, 2013 Excess phosphorus (P) has accumulated in Japanese paddy soils, due to fertilizer P inputs over crop requirement for several decades, and improvement of the excess of P is necessary in view of environmental conservation.

Fertilisation with compost: effects on soil phosphorus sorption and on phosphorus availability in acid soils. [PDF]
, 2019 Phosphate mineral fertilisers are manufactured from non-renewable resources.Soil fertilisation with composts is considered a good source of reuse nutrients such as phosphorus (P).

Soil nitrogen affects phosphorus recycling: foliar resorption and plant–soil feedbacks in a northern hardwood forest [PDF]
, 2015 Previous studies have attempted to link foliar resorption of nitrogen and phosphorus to their respective availabilities in soil, with mixed results. Based on resource optimization theory, we hypothesized that the foliar resorption of one element could be

Cover Crops and Soil Phosphorus Availability
Communications in Soil Science and Plant Analysis, 2017 Plants affect soil phosphorus (P) solubility through root exudates, but studies are lacking on species used as relay or cover crops in tropical environments. We evaluated the effect of cover crops on soil phosphorus (P) availability in an oxisol. Ruzigrass (Brachiaria ruziziensis), pearl millet (Pennisetum glaucum), peanut (Arachis hypogaea), crambe ...

Metagenomics of the Effect of Long-Term Straw Return on the Phosphorus Cycle in Meadow Black Soil
Agronomy, 2023 Returning crop straw to the soil is an effective measure to increase soil fertility and maintain crop yield in agroecosystems. In this study, we conducted a 34-year field experiment (1984–2017) to investigate the relationships among the impacts of straw ...

Human alteration of the global nitrogen and phosphorus soil balances for the period 1970-2050 [PDF]
, 2009 The Millennium Ecosystem Assessment scenarios for 2000 to 2050 describe contrasting future developments in agricultural land use under changing climate. Differences are related to the total crop and livestock production and the efficiency of nutrient use

Fractional Modeling for Quantitative Inversion of Soil-Available Phosphorus Content
Mathematics, 2018 The study of field spectra based on fractional-order differentials has rarely been reported, and traditional integer-order differentials only perform the derivative calculation for 1st-order or 2nd-order spectrum signals, ignoring the spectral ...
