Nonetheless, the acquisition and processing of soil samples are labor-intensive and time-utilizing, and the related cost remains high-priced to farmers. Artificial intelligence is the most speedily growing area combined into approximately all aspects of human life. Soil macronutrients like nitrogen (N), phosphorous (P), and potassium (K) have a significant role in precision agriculture. There is a huge need for powerful and rapid measurement systems to measure accurately the macronutrients in the soil for optimal crop productivity, especially in site-specific crop management system, where the application of fertilizer can be regulated spatially with respect to crop demand. Nevertheless, it can present a research direction to design an advanced scheme in order to predict the properties of soil. A portable sensor device is a basic need of an agriculture system for the accurate and rapid monitoring of soil macronutrients.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Aim</h3>\u0000 \u0000 <p>In this research, the soil nutrients identified from the collected soil samples using optical sensors are evaluated for their accuracy using a deep learning approach.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>A deep residual network is exploited for the soil nutrient prediction after augmenting the gathered soil data.

Iron deficiency disrupts major metabolic and cellular activities such as respiration, DNA synthesis, and chlorophyll synthesis. Iron also activates various metabolic pathways and is vital to numerous enzymes. Iron is widely distributed in soil, but plants do not readily absorb it. In addition to neutral pH, Fe also forms insoluble Fe complexes under alkaline conditions. The fundamental cause of Fe chlorosis is an imbalance between the solubility of Fe in soil and the demand for Fe by plants. Various Fe fertilizers, including organic, chelated, and inorganic, are administered to the soil and leaves to treat Fe deficiency and chlorosis. Currently, used Fe fertilizers are expensive, easily adsorb on soil particles, and cause Fe to leach out of the soil with water, thereby diminishing their efficiency. They also need to be applied repeatedly, resulting in an excessive Fe fertilizer concentration in the soil that can cause harm to the plants. The usage of Fe nanofertilizers in agricultural production has expanded to address the disadvantages of existing Fe fertilizers. The advantages of nanosized Fe fertilizers include their physical and chemical characteristics, such as the high surface area to volume ratio that aids in easy absorption by plants’ roots and leaves. Controlled-release iron oxide nanofertilizers supply the regulated release of nutrients in a way that is coordinated with the nutritional needs of the crops. This improves the accumulation of nutrients in the plant, filling in the gap of nutrient deficiency and lowering environmental risks due to leaching. The possibility of iron oxide nanoparticles as Fe micronutrient fertilizers, their uptake and mechanism of action, advantages, and limitations are critically highlighted in this review article.</p>","PeriodicalId":16802,"journal":{"name":"Journal of Plant Nutrition and Soil Science","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2023-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138505783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Large and high-quality potash deposits are found in the Northern Hemisphere in Europe, Canada, Russia, and Belarus. From around 1950 onward, the industry began to grow strongly. In 2021, the global production was about 36 million t K. More than 90% is marketed as fertilizer, mainly potassium chloride.

Dicot plants respond to insufficient B supply by altering root architecture and root hair growth. How root systems of rather low‐B demanding monocot species such as maize ( Zea mays L.) respond to B deficiency in terra has not been experimentally resolved, yet. Aims The study aims to investigate root responses and their physiological consequences under B deficiency during the vegetative growth of maize. Methods B73 wild‐type (WT) maize and its root hairless rth3 mutant were grown under varying B supply conditions in soil columns and in an automated root phenotyping facility. Biomass data, root system architecture traits, the mineral elemental composition and molecular B‐deficiency responses were quantified. Results Though having very low leaf B concentrations, no major growth deficit, apart from chlorotic stripes on leaves, was recorded on maize root and shoot development, with or without root hairs, on B‐deficient conditions. Although leaf B concentration of the rth3 mutant is significantly lower under B‐deficient and under B‐surplus conditions compared to the WT, the rth3 mutant neither developed a larger total root length, more fine roots nor displayed a higher expression of B uptake transporters as compensatory adaptations. Conclusions Strikingly, maize plants did neither react with an inhibited root growth nor by a compensatory root foraging behaviour to severe B‐deficient in terra growth conditions. This is rather atypical for plants. The performance and altered leaf B concentrations of rth3 mutants may be biased by secondary effects, such as an overall reduced root growth.","PeriodicalId":16802,"journal":{"name":"Journal of Plant Nutrition and Soil Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135285712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
