Summary: The study found that acidification treatment can increase the release of nutrients in BGR and significantly improve the dry matter production of juvenile maize. The application of acidified BGR can increase the phosphorus and manganese content in the soil, and improve fertilizer efficiency.

Summary: Plants can only absorb a limited amount of nutrients from the soil, so foliar fertilization using sulfuric bone meal hydrolysate has been proven to be a good alternative. In this study, the effects of foliar application of neutralized sulfuric bone meal hydrolysate on soybean growth parameters and nutrient concentrations were evaluated. Results showed that soybean plants treated with 1% NSBMH had significantly improved growth and nutrient concentrations compared to the control group. Therefore, recycling cattle bone waste to obtain alternative phosphorus through neutralized sulfuric bone meal hydrolysate is a sustainable and environmentally-friendly option.

Summary: A pot experiment was conducted to investigate the effect of co-application of phosphorus (P) and/or potassium (K) fertilizer on the growth of Mung bean. It was found that adding potassium to a phosphorus-enriched soil layer increased root proliferation and improved nutrient uptake. Furthermore, shallow co-application of P and K resulted in increased shoot yield and nutrient content compared to individual P application.

Summary: This study compared the seasonal patterns of physiological parameters and nutrient concentrations in different citrus cultivars during fruit ripening. The results showed that late-maturing cultivars had significantly higher photosynthetic CO2 fixation rates compared to middle-maturing cultivars in December. Seasonal changes in nutrient contents differed between middle and late-maturing cultivars, with the differences being more pronounced in leaves than in roots. The study concluded that seasonal differences in physiological parameters and macro-nutrient contents of citrus cultivars are largely determined by seasonal fruit ripening.

Summary: Nitrogen availability and form significantly impact N uptake and assimilation in plants, with barley showing better growth under inorganic nitrogen (NO3-). Wild barley, particularly XZ179, appears to have a higher tolerance to organic nitrogen (glycine) compared to cultivated barley. Ammonium adversely affects growth parameters in both wild and cultivated barley genotypes.

Summary: This study examined the impact of wastewater treatment plant (WWTP) discharges on nutrient concentrations in receiving rivers in Sao Paulo state, Brazil. The results showed that WWTP discharges significantly increased nutrient concentrations and loads, with limited net nutrient uptake along the river reaches. These findings suggest that WWTPs with limited nutrient removal have considerable effects on water chemistry and nutrient cycling, potentially impairing downstream ecosystems.

Summary: Global phosphate mines are depleting, leading to an increasing interest in using struvite precipitation as a slow-release phosphorus fertilizer. This study assessed the effect of struvite/biochar composites as slow-release phosphorus fertilizers on maize growth and nutrient uptake, and calculated phosphorus use efficiency. The results showed that the struvite/biochar composite with high amounts of biochar was the most effective in improving maize growth and nutrient uptake.

Summary: This study found that higher phosphorus application led to increased shoot biomass and grain yield of cowpea plants in the field experiment, but did not significantly affect shoot or grain zinc content. There was no significant correlation between grain yield and zinc content under high soil phosphorus levels. The impact of higher phosphorus application on reducing plant zinc content may be genotype-dependent.

Summary: Potassium is the key element for improving fruit quality, and this study aimed to determine the best type of potassium fertilizer for grape growth and nutrient uptake. Four types of potassium fertilizers, including complex fertilizer, potassium nitrate, potassium sulfate, and potassium dihydrogen phosphate, were applied to grapevines in plastic pots to explore their effects. Results showed that complex fertilizer and potassium nitrate increased grapevine biomass, while the other fertilizers had no significant effect. Only potassium nitrate increased the contents of photosynthetic pigments in leaves. All fertilizers increased total P and K contents in grapevine plants, with potassium dihydrogen phosphate being the best choice.

Summary: Photo-respirometric techniques are used to evaluate photosynthetic activity in phototrophic organisms. This study examined the impact of nitrate, ammonium, and phosphate availability on the photosynthesis and respiration of Scenedesmus almeriensis, finding both increasing until saturation and then diminishing, with inhibition at high concentrations. Various equations were used to model the data and determine nutrient yield coefficients, showing that nitrogen and phosphorous coefficients are not constant and can be affected by nutrient concentrations, including luxury uptake phenomena.

Summary: A composite biochar and hydrophobic biofilm were proposed to synergistically control nutrient release and provide essential nutrients for crop growth. The optimized preparation of composite biochar and exploration of nutrient loading mechanism were carried out, showing significant advantages in promoting crop growth. The constructed carrier and co-release system showed promising effects on early maize growth and demonstrated potential for sustainable agricultural economy.

Summary: This study investigated the effects of water-soluble organic matter from different organic materials on phosphorus immobilization and plant phosphorus uptake. The results showed that water-soluble organic matter derived from cattle manure compost, sewage sludge compost, and hydrothermal decomposed liquid fertilizer can suppress phosphorus immobilization and improve phosphorus uptake efficiency. It was also found that higher available phosphorus levels in the soil were associated with reduced root development in plants.

Summary: Understanding the role of soil microbes and their associated extracellular enzymes in grassland nutrient dynamics is important for assessing the functioning of grassland ecosystems. This study found that the application of superphosphate and lime influenced the microbial diversity and enzyme activities in nutrient-poor grassland soils, which in turn affected nutrient bioavailability.

Summary: Mineral nutrient deficiencies have a significant impact on tomato plant development, affecting root morphology, biomass, and chlorophyll a fluorescence. The lack of phosphorus and potassium reduces root mass density and impairs the growth response of tomato plants. Furthermore, the content ratio of phosphorus and potassium is positively correlated with root volume.

Summary: Accurate modeling of hydrological processes in the soil-crop system is crucial for assessing the impacts of soil management and climate change. The use of empirical treatments in water flow processes limits the applicability and increases prediction errors in crop models. Physics-based descriptions are available, but their significance is often overlooked.

Summary: This study investigated the potential use of inorganic soluble polyphosphates (Poly-P) as slow-release fertilizer in drip fertigation. The results showed that Poly-P fertilizers can reduce the mobility of P in the soil while maintaining its availability. Weekly fertigation exhibited the best results in terms of P availability. Using Poly-P fertilizers can reduce the frequency of P application in drip fertigation and ensure high crop yields.

Summary: Summarizing information from large bodies of scientific literature is an essential but work-intensive task. This study explores three NLP techniques (topic modeling, tailored regular expressions, and the shortest dependency path method) to support evidence synthesis tasks. The results show that all three tested NLP techniques are able to support this task and have the potential for automated updating as new publications become available.
