What is the role of microorganisms in soil fertility and crop productivity and does climate affect soil organisms and soil microbial plant interactions?
hello, According to some studies, the direct effects of climate change act on organism process rates and inorganic resource availability. Also by functional traits of plants, microbes and other organism thus indirectly influencing carbon pools and feedbacks.
Microorganisms play a crucial role in soil fertility and crop productivity. Microbes help to break down organic matter in the soil, releasing essential nutrients for plant growth and development. They also help to control pests and diseases, and improve soil structure and water retention. Climate does have an effect on soil organisms and soil microbial plant interactions. Changes in temperature and moisture levels can affect the growth and activity of soil microorganisms, which can impact the availability of nutrients for plants. For example, increased temperatures and drought can reduce microbial activity, leading to decreased nutrient availability, while increased rainfall can increase microbial activity and nutrient availability.
Besides n and c cycles the number and activity of soil microbes inhibit the pathogenic potential in soil
Soil microbe are greater In both number and diversity in high organic matter soil this can promote primary plant health by pro biotic and antibiotic mechanisms
Beside health effect
Accurately
Assessing soil organic constitutes a mechanism to stop and reduce the over enrichment of our atmosphere with greenhouse gasses
Most nutrient release from organic matter is carried out by soil microbes. Microorganisms utilise the carbon and nutrients in organic matter for their own growth as they break it down. They discharge extra nutrients into the soil so that plants can absorb them.
Yes its facts that soil microorganisms are responsible for most of the nutrient release from organic matter. When microorganisms decompose organic matter, they use the carbon and nutrients in the organic matter for their own growth. They release excess nutrients into the soil where they can be taken up by plants. Moreover, micro-organisms are the most essential resource for a farmer because they nourish soil with essential nutrients. Soil contains numerous minerals in forms which plants cannot absorb directly. Microbes like fungi and bacteria with the help of their enzymatic machinery break down these minerals into forms that can be absorbed by crops and within food plant cropping systems, microorganisms provide vital functions and ecosystem services, such as biological pest and disease control, promotion of plant growth and crop quality, and biodegradation of organic matter and pollutants. Due to their close proximity to plant roots, soil microbes significantly affect soil and crop health. Some of the activities they perform include nitrogen-fixation, phosphorus solubilization, suppression of pests and pathogens, improvement of plant stress, and decomposition that leads to soil aggregation. Interactions among plant and soil communities may be unpredictable when observing their responses to natural fluctuations in climate or at a single time point. Due to the temperature sensitivity of carbon cycling processes, small changes in temperature could result in a large release of soil carbon back to the atmosphere. Climate change has a potential effect on soil microbial biomass; organic matter decomposition, net primary production, nutrient cycle, vegetation and precipitation, on local and global regime and climate warming can reduce the diversity of microbes, increase the complexity of their relationships, and speed up their decomposition of soil organic matter.
The role of microorganism is to hasten organic matter decomposition which in essence improves the soil nutrients which ultimately improve crop productivity. Climate change and its effect can affect soil microbial activity i.e. displacement of the soil through soil erosion. Climate change effects change the biodiversity which reduces the interdependence between organisms. e.g the symbiotic relationship between rhyzobia becta and legumes
Micro organisims plays a crucial role in stabilisation of soil aggregates!
Micro organisims plays the termindous role in the nutrient cycling, nodule formation for legumes, conversion of dead organic materials into plant available form and increase crop productivity.
Climate change can affect the formation of the soil itself and then any form of life within it!
Example Dinitrification
# climate change can make effective micro organisims pathogens or deases!
Microorganisms in the soil play important role in soil fertility, in soil microorganism discomposed soil organic matter and make available to the plants .Also various microorganism are involved in nitrogen fixation which fix the atmospheric nitrogen by nitrification process i e change atmospheric nitogen into nitrate and nitrite which is plant available form of nitogen.
Your words are very true, my dear Aakriti Khatiwada... Therefore, we see that microorganisms spread in the soil from the smallest organism of protozoa, arthropods, nematodes, mites, and colimus to beetles, earthworms, ants, and even large animals that hide, aerate the soil and increase its fertility, By breaking their symbiotic fungal elements, rock particles, and soil particles apart by growing in pores and fissures, secreting substances that etch surfaces of rock and soil particles, feeding microorganisms that liberate minerals, inevitably at some point, animals will consume plant roots and open passages where Soils absorb air and water. Some, like earthworms, grind up soil particles in digestion processes. They also recycle plant material as fertilizer, building soil fertility and feeding more growth. This softens the soil and builds crumb structure, tillage, and retains moisture and nutrients. While allowing water and air to penetrate the roots, on the contrary, continuous grazing, not to mention the impact of man and machines, man presses the soil and reverses these gains. .
Não podemos esquecer de que os microorganismos funcionam também como grande reservatórios de nutrientes retidos nas suas composições celulares. Com a morte desses mesmos microorganismos, os nutrientes são liberados para o solo e, consequentemente, as plantas utilizam. Em regiões de clima tropicais é, uma das possíveis alternativas de reduzir a lixiviação, perdas de nutrientes e, redução dos custos de produção.

They increase soil fertility by incorporating air, minerals and nitrogenous compounds. They contribute in increasing plant growth by providing essential elements, minerals that plants cannot utilize by their Owen. Microorganisms decompose organic matter to simpler form that can be easily uptake by plants. Climate warming can reduce the diversity of microbes, increase the complexity of their relationships, and speed up their decomposition of soil organic matter. Warmer temperatures affect the densities of airborne microbes and can accelerate their long-distance transport. Higher temperatures and environmental stresses can also alter human and animal physiologies and defenses against pathogens. Climate change can disrupt the match between organisms and their local environment, reducing survival and reproduction and causing subsequent impacts on populations or species' distributions across geographic regions.
Los microbios del suelo, juegan un rol muy importante en la dinámica de los ciclos biogeoquímicos de los nutrientes, el efecto del clima sobre éstos sería mediante el impacto sobre los cultivos que puede afectar los proceso metabólicos de la fotosíntesis que es la vía mediante estos microbios obtienen la energía, y que podrían verse favorecidos un cierto grupo de microbios y por ende la diversidad de microbios del suelo, fundamental para el desarrollo de los cultivos, y un cambio en la interacción con las plantas.
I agree with this view Soil microorganisms are responsible for most of the nutrient release from organic matter.
