Why is topsoil important in crop production?
Topsoil provides a seedbed for the germination of seeds (currently an expensive input item) and the establishment of a rooting system for the crop. It supports a complex community of beneficial micro-organisms playing a vital role in the decomposition of plant residues and the recycling of nutrients.
Why is topsoil best for plant growth?
The top soil particles are finest and porous so that it allows more water to retain in it. The top soil is darker in colour due to the presence of humus which makes it fertile and best for plant growth.
Is topsoil good for farming?
The study estimated that about 35 percent of the region has lost its topsoil completely, leaving carbon-poor lower soil layers to do the work of supporting crops. Having thick, healthy topsoil means plants can grow faster and healthier, increasing crop yields and keeping the field’s ecosystem running smoothly.
What is the best soil for crop production?
Loamy-
Loamy-textured soils are commonly described as medium textured with functionally-equal contributions of sand, silt, and clay. These medium-textured soils are often considered ideal for agriculture as they are easily cultivated by farmers and can be highly productive for crop growth.
Is thick topsoil good for farming?
Why is good soil important for crop production?
When it comes to the end, making a good soil is more important for the crop production. By adjusting your soils pH, texture and fertility to your liking plants, you can create the good soil. Your plants will find what your pH of soils should be.
How does the health of the soil affect plant growth?
The complex biological, physical, and chemical interlink of a healthy soil can influence plant water availability under dry conditions, off-field nutrient losses to nearby streams during rain events, and the availability of nutrients through nutrient cycling for food and fiber production.
How does loss of topsoil affect crop productivity?
Figure 1. Reduction in crop productivity from loss of topsoil. Data were primarily collected on soils without adequate fertilizer treatment. As the topsoil erodes, infiltration rate and water availability become limited.
What’s the difference between soil and topsoil for gardening?
There might also be a difference in topsoils intended for landscaping vs gardening vs farming applications. Different topsoils might also contain different mixes of soil types – such as sand, silt and clay.
Why is soil health important for crop production?
Soil Health Benefits for Sustaining Crop Production. The benefits of healthy soil in sustaining crop production are most evident when growing conditions are less than ideal. Healthy soils increase the capacity of crops to withstand weather variability, including short term extreme precipitation events and intra-seasonal drought.

Which is the best soil type for agriculture?
Silt – This soil is smooth and holds onto water well, but not as well as clay. Because it holds onto moisture, it doesn’t drain the best, which can be a problem for many crops.
