Like other plants, pasture grasses also require nutrients to grow. Only through proper fertilization can pasture grasses grow better and better, thus contributing to high yields. Currently, the pasture grasses cultivated in China are mainly legumes and grasses. So, what kind of fertilizer is best? Details are as follows:
What is the best fertilizer for growing pasture?
The fertilizers used for growing forage grasses vary depending on the type of forage grass. For example, legume forage grasses have their own nitrogen-fixing ability, which can basically meet their own needs, so only the phosphorus and potassium ratio needs to be considered when fertilizing them; while for grass forage grasses, the ratio of nitrogen, phosphorus, and potassium needs to be considered comprehensively, especially nitrogen fertilizer, which has a more significant effect on increasing yield.
How should you fertilize pasture?
1. Base fertilizer
Organic fertilizers , such as pig manure, cow manure, stable manure, and compost, are preferred for base fertilizer. Apply 2,500 kg per acre. Base fertilizer should be applied twice a year (in winter and spring).
2. Seed fertilizer
Seed fertilizer is applied simultaneously with the seeds at the time of sowing to meet the needs of forage seedling growth. It can be applied in the sowing furrow or hole, covering the seeds, or used for soaking or coating seeds. Generally, compound fertilizers containing nitrogen, phosphorus, and potassium can be chosen as seed fertilizers . When applying fertilizer, care should be taken to avoid direct contact with the seeds to prevent damage.
3. Topdressing
Chemical fertilizers are mainly used for topdressing pasture, but nowadays, supplementing with well-rotted human excrement or manure yields better results. Topdressing is generally applied after tillering, jointing, budding, and each harvest. Methods of topdressing include broadcasting, strip application, hole application, foliar spraying, irrigation, and foliar application. For foliar application, the concentration should not be too high, limited to avoid harming the crop. When applying micronutrients, the dosage is 30-70 grams per acre.
