In arid areas, the effects of grazing have deteriorated native grasslands significantly, resulting in a substantial loss of plant life and the gradual loss of soil. There are also abandoned agricultural lands that are unproductive, which is subject to erosion, due to the continual soil deterioration. Restoring grassland is one of the most crucial pasture improvement practices that comes in the form of establishing vegetation through spreading fodder seeds that are modified according to unique climatic and soil conditions.
WHEN SHOULD YOU CARRY OUT PASTURE RESEEDING?
This technique must be performed when there is a dramatic reduction in the cover and structure of the species (good forage) and/or the risk of erosion. Recovery of grassland may also occur if the pastures are decent and have the potential for the quantity and quality of vegetation by reseeding. For more information on reseeding, contact the best seed company.
WHICH AREAS NEED REPLANTING?
The areas with fertile, moderate soils where yearly precipitation is at least 300 mm and highly deposited fields with good potential are highly susceptible to this practice. Also, real recovery is fairly slow. An excellent location for establishing a reseeding grassland is also the growing areas which were deserted.
WHAT SPECIES DO YOU USE IN REPLANTING?
Species used in the seed will be based on their adaptation to the soil-and climactic attributes, based on the selection process of the forage species used in a seed. Replanting grass is the most standard operating procedure in grassland rehabilitation; however, some forage trees can be used as well.
WHEN SHOULD OVERSEEDING BE PERFORMED?
Grassland reseeding is needed once the rainy season has been determined to ensure optimal soil moisture content a vital planting period. The planting period can fluctuate between the end of June and the end of July.
HOW SHOULD SEED PLANTING TIME BE DISTRIBUTED?
Grass seed may be filtered manually or mechanically, according to resource scarcity (equipment and implements) and surface area, by broadcast or groove. You can use sowing of grain and other small or specialized seeds of grass to seeding with machinery. The depth of the plantation depends on seed size and soil condition and differs from 0.5 to 2.5 cm. The small planting should be shallower than the large planting seed. Similarly, the depth of planting of clay soils ought to be lower than that of sandy soils. Light harrow shrub branches may be used for covering the seed.
HOW SHOULD ALREADY-ESTABLISHED RESEEDING BE MANAGED?
After the reseeding of grassland is done, the next part of the solution process is to enable the growth of some species, at least for another two years by excluding grazing of those areas. At the end of the second grazing plant growth cycle, a light herbicide can be provided. In the reseed area, the herbicide must be attributed in 500 grams per acre if there is an issue of weed overgrowth.
REASONS FOR SOIL EROSION
Natural soil erosion is primarily caused by the region’s climate and geological processes but can be significantly speeded up by human practices in agriculture.
The surface layer damage rate is affected by the following:
• Climate characteristics. Water erosion is characteristic of areas with continuous heavy rains as well as rapid spring arrival and heavy snow melting. The water melted in this way erodes the earth and causes valuable soil damage. Wind erosion is typical in lowlands with a dry climate as the soil dries quickly due to the little rain.
• Functions of relief. Furthermore, how destructive processes that start developing on convex slopes more quickly than on the concave surface depends upon the steepness and length of slopes. On plains where vegetation is minimal, erosion develops more quickly.
• Soil characteristics also play an important role in the speed of erosion. The most stable black soil was considered so that the soil is virtually lost and is not eroded. The gray soil has the lowest resistance and under certain conditions is quickly eroded.
• The vegetable layer’s presence. The roots of plants also protect the soil against water and wind and allow for rapid moisture absorption and prevent drying of the soil even in warm weather. The wind speed is lowered near the ground and prevents weathering of the ground.
• One of the most harmful factors remains in human activity. In violation of crop rotation rules, uncontrolled grazing on the same territory, plowing in the soil, and field development all leads to land injury and recovery is extremely difficult.
The selection of methods to deal with other types of erosion is needed and the reasons must be taken into account. Sustainable results and soil protection can only be achieved in addressing the causes.
