Yes, organic manures and bio fertilizer improves the texture of the soil, increases air gaps, enriches the soil with nutrients and also improves the ability of soil to hold water.They also improve the soil structure by increased permeability, cation exchange capacity and aggregate stability, and a decreased bulk density. Associated benefits are thus a higher infiltration and moisture and nutrients retention, and better plant growth. Regular application can lead to long-term improvements in soil fertility, texture, and overall health. They promote the development of soil-aggregating bacteria, enhancing soil structure.
Also a clear yes that organic amendment and higher organic matter can transform to physical, chemical and biological capacity of soils.
In terms of the physical mechanism organic matter has a lower bulk density measured in grams per cc it works to expand the open space of the soil medium.
As stated the more open porous texture improve percolation giving better water penetration into the soil.
Secondly the open porous texture combines with a chemistry which retains the water in the soil. In addition water the open texture allows for better aeration necessary for root growth.
The ability to have lower density is a function of large water stable aggregation. The aggregates are fostered by roots which lasso the particles ans stablize them. in addition the clay and organic aggregates are favored by cationic interation with this anionic complexes.
Biologically the ability of mycorrhizal fungi to favor organic matter persistence is favored by the hydrophobic and non degrading nature of the glomalin glycoprotein complex.
Compacted soil structure can issues of chemistry need remediation to allow the fundamental biology to function optimally. So regenerative management starts with plans to eliminate the physical, chemical and biological constraint.
Much of the physical issues which soils are function of the tillage employed and tilling at inappropriate timing and condition.
Profile analysis is critical to understanding the presence of physical constrants. On the chemical level soil and plant analysis is useful. The holistic solution will demand a soil conservation and erosion control strategy and the prevention ability to promote drainage and watering.
The biological function appreciation for the diversity of plant and animal systems is important for sustainable regenerative and profitable system development and implementation.
When initiating biologically based systems the dependence on toxic agrichemicals need to be avoided as this antithetical to biology and diversity fueling the system.
The proper system development will transform the soil system when done properly and this is best done systemically with thought baselining monitoring and modifications for changing conditions.
Biological fertilization can rely heavily on legumes and other soil building plants and the recycling of animal manures and composts along with rotation animal to plant systems in a rotational sequence.
Crop sequences can lower animal pests and problems and likewise the animal production definitely favors crop and plant production.

If you meant 'particle size distribution' rather than field texture, the answer would be different
Although they won't significantly alter soil texture, organic manures and biofertilizers can help the structure of the soil. The percentage of sand, silt, and clay particles in the soil is referred to as the texture of the soil and is influenced by the parent material as well as geological processes. But over time, organic matter from these sources can boost soil fertility, water retention, and microbial activity all of which will indirectly improve soil quality
Yes, soil texture changed with the use of organic manures and biofertilizers into the soil system in the form of Vermicompost, Farmyard Manure (FYM) and Green Manures etc. There are many reports that proves physicochemical parameters (PCPs) of soil get changed due to use of organic manures and biofertilizers. Along with this, they also increase soil fertility, water holding capacity, soil-aeration, growth of beneficial microorganisms etc. for the growth and development of soil plants.
Soil texture, defined by the proportions of sand, silt, and clay, is a stable property that isn't easily changed. Although organic manures and biofertilizers don't alter soil texture, they can significantly enhance soil structure and health. They improve soil aggregation, increase organic matter, boost microbial activity, enhance water retention, and improve nutrient availability.
Desde el punto de vista de la física de suelos, la textura es una propiedad que considera los contenidos porcentuales de arena. limo y arcilla y su análisis implica eliminar cualquier componente orgánico por lo tanto , no se puede cambiar con ningún material orgánico, porque no corresponde, lo que se puede modificar es la estructura del suelo mas no la textura que es otra cosa. por lo tanto la respuesta es negativa.
Soil texture is a qualitative term and assessed by the proportions of soil mechanical fractions viz. sand, silt and clay. So, the soil texture cannot be changed by adding organic manure or bio- fertilizer.
Dear Samarpita, As u know percentage of clay, silt and sand define the soil texture. The latter influences the ease with which water and air can enter and move thru soil. Addition of OM thru organic manure decreases the dispersible clay content and increases wet aggregate stability (but low in high clay content soil) of soil. Results in favourable soil aeration, improves soil porosity, increases soil strength indices. Also results in better soil temperature conditions and enhanced microbial activity. As humus constitutes 33-50 percent of stable OM, it serves as a source of energy for microbes. Hope u may get an answer to ur query.
