Phosphorus resources, both in phosphate rocks and the soil, are limited. However, effective food production is not possible without use of P fertilizers. Recognizing eliminating or at least ameliorating factors (hot spots) that interfere with uptake phosphorus (P) by crop plants key importance for nitrogen (N) on farm. Plants have developed many adaptation mechanisms to their environment, i.e., soil low available phosphorus. The most important ones include secretion organic compounds into rhizosphere association plant roots microorganisms. A classic example mycorrhiza. These can be used farmer sequentially select rotation. inorganic (Pi) from reduced environmental (temperature water) (low content phosphorus, acidity, compaction). responsible growth size root system. Mitigating these negative effects improves efficiency soil. second group critical factors, limiting availability effectively controlled using simple measures (for example, lime).

Secondly, multiply productivity applied mineral fertilizers through targeted recycling: rotation, residues, manure.

Soil acidification adversely affects plant growth and development by decreasing the accessibility of roots to essential nutrients. Thus, it decreases crop yield. However, there has been a lack systematic research on how soil influences nutrient absorption in eggplant cultivated greenhouse. To address this gap, an experiment was conducted greenhouse with seven different acidity levels (4.5, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5), achieved adding dilute H2SO4. The findings indicated that organic matter (SOM) content at pH 4.5 decreased 49% - 50% compared 7.0 7.5. In addition, exchangeable aluminum (Al3+) electrical conductivity (EC) were highest 4.5, increases 82 -88 mg kg-1 1.78 1.82 ms cm-1, respectively, total nitrogen (TN), phosphorus (TP), potassium (TK) declined as increased, reaching their lowest 0.59, 0.42, 3.79 g 4.5.

Borehole hydraulic fracturing in coal seams can prevent dynamic mine disasters and promote the sustainability of mining industry, microseismic signal recognition is a prerequisite foundation for monitoring technology that evaluates effectiveness fracturing. This study constructed ultra-lightweight CNN models specifically designed to identify waveforms induced by borehole seams, namely Ul-Inception28, Ul-ResNet12, Ul-MobileNet17, Ul-TripleConv8. The three best-performing were selected create both probability averaging ensemble model voting model. Additionally, an automatic threshold adjustment strategy identification was introduced. relationships between feature map entropy, training data volume, performance also analyzed. results indicated our in-house surpassed InceptionV3, ResNet50, MobileNetV3 from TensorFlow Keras library. Notably, achieved improvement at least 0.0452 F1 score compared individual models. enhanced threshold’s precision 26 decimal places. However, continuous zero-entropy value maps various channels found detract model’s generalization performance. Moreover, expanded dataset, derived thousands waveforms, proved more compatible with comprising hundreds parameters. findings this research significantly contribute prevention disasters, potentially reducing casualties, economic losses, promoting sustainable progress industry.

Faba bean (Vicia faba L.) is an important legume crop grown worldwide, especially under rainfed conditions. beans require phosphorus (P) fertilization to maintain high N2 fixation rates and obtain yields. However, farmers in many countries use low quantities of P because its cost the risk drought, which reduces crop’s response fertilization. The objective present study was determine effect on two cultivars, examining several key traits identify most efficient genotype. Seed yield influenced by main variety, two-way interaction between year three-way among year, treatment, variety. In KK-14 cultivar, seed increased 99% during first year. Similar trends were observed for components. Additionally, morphological physiological characteristics affected treatments cultivars Therefore, appropriate along with proper management cropping systems, can significantly impact growth, biomass yield, productivity different conditions, leading higher yields greater economic returns farmers.

Phosphorus is a key limiting factor for plant growth. Several approaches are developed to mitigate the impact of P shortage on plants and selection crops with high mobilizing capacity from P-deficient soils. In this work, four Medicago truncatula genotypes (A17, TN8.20, TN1.11, TN6.18) were compared their efficiency cope conditions using several criteria. Significant differences between genotypes, deficiency treatments, interaction treatments found. limitation resulted in an important decrease shoot biomass, content, use efficiency, photosynthetic parameters.
