Fertilizing the grassland
Grassland Grass can only grow well if sufficient nutrients are available for plant roots. Mowing the grassland is necessary to increase the number of nutrients in the grass. It should be noted that the nutrients are available in the correct proportions for the plant. The purpose of grassland fertilization is:
- To increase the grass production
- Ensure that the produced grass is tasty and of a good composition.
The optimal fertilization depends on the grassland use. When buried only, little nutrients are discharged and the fertilizer of the grassland may be much smaller than mowing. A large fertilizer is required if the plot is first hatched in spring. How often fertilized is your own choice when fertilizing once, this may be the best in April / May. When a grassland is fertilized twice, the second time may be the best in August.
Animal manure has an excellent fertilized value. The advantage of animal manures is that fertilizers from the manure spread throughout the pasture season. Precisely because this is so slow, your pasture benefits throughout the season. For a horse meadow 10 m3 per hectare is sufficient. Otherwise, there will be an excessive potassium content, which makes it difficult for grass to absorb magnesium and other important trace elements for horses.
There are special fertilizers for horse meadows for sale. The nitrogen is released very slowly: in 2-3 months, this form of nitrogen is called ENTEC nitrogen and is made by BASF. Nitrogen in normal fertilizer will be released within a few days after spreading. Consequence: a huge growth spurt and relatively high protein levels in the grass, which is not good for horses.
When you grow grass or lucerne on a contract basis for Hartog, look for fertilization at Grass cultivation information or Lucerne cultivation information for more information on this.
Mowing the grassland must be tailored to the soil's nutritional condition. Below is the supply of nutrients present in the upper centimeters (0-6 cm) of the soil.
Fertilization advice is calculated using soil analysis. The fertilizer recommendation is calculated for three consecutive years. The calculation of the advice takes into account the spillage losses during the intermediate winter periods and with any fertilizers already carried out. At Ground Care and Laboratory you can get soil analysis and fertilization advice.
The following nutrients are absorbed by the grass in large amounts:
Nitrogen is the basic element for the construction of the vegetable protein. It is the grass growth engine. Spilling of nitrogen from the soil is easy, so it is advisable to administer nitrogen several times a year. This ensures that there is sufficient grass growth throughout the growing season. On horse meadows, the nitrogen fertilization should not be too high, the grass becomes too protein rich and too weak on crude fiber that can cause bowel disorders.
Phosphorus is used in the plants for the construction of certain proteins and other organic substances, it promotes root growth. For the health of the grazing livestock it is important to achieve a sufficiently high phosphorus content in the grass. The leaching of the soil is low, by fertilizing a reserve of phosphorus can be built into the soil. On horse meadows, phosphorous fertilization can take place best in early spring (March). Phosphorus is used by the horses for bone formation and energy efficiency.
Potassium does not form an ingredient of the organic substance in the plant. It plays a role in the formation and transport of carbohydrates (including sugars) and in the regulation of water management in the plant. In case of lack of potassium, the grass becomes sensitive to drought and frost and excess potassium can result in poor mineral supplies for the horse. It is recommended to administer potassium fertilizer twice, the highest dose in the spring and the second dose in the period June-July.
Magnesium is necessary for the plant for the growth of the leaf green. It is important to keep the magnesium content in line with animal health. Magnesium is hardly absorbed by the plants in cold weather conditions. It is therefore advisable to submit two thirds of the recommended dose in the spring and one third during the month of August.
Calcium is important for the plant for the strengthening of the cell walls and for the neutralization of organic acids. For horses, calcium is necessary for bone formation and muscle contraction regulation. For the soil, calcium is especially important in terms of soil structure and acidity. When the soil is too acidic, the nutrients for the plants are poorly absorbable. By calcification the soil becomes less acidic and the calcium level is leveled. Bekalking occurs preferably in late autumn or early spring.
Sodium does not affect grass growth, it makes the grass more appealing to horses and it provides for the supply of horses to horses. Sodium is very poorly retained in the soil. It is therefore necessary to administer sodium to the soil annually. This can be with agricultural salt or fertilizer.
