I want to raise alfalfa to make alfalfa fertilizer for lawns, I need a lots of them. Maybe you are in my position, too. There are some tips of preparation of sowing alfalfa.
1. Site choice
Hay wide flexibility, as warm and semi-sticky climatic conditions, the dirt necessities are not strict, aside from too substantial soil, amazingly thin sand and peracid or over-soluble base soil can develop, it is most appropriate for profound soil Growing in free, calcium-rich topsoil. Horse feed ought not be planted in solid corrosive and basic soil. It lean towards nonpartisan or soluble soil. The pH is ideally 7~8, the salt substance is under 0.3%, and the groundwater level is beneath 1m. At the point when the dirt pH is underneath 6, the knob can't frame, and when the pH is 5 or less, it can't develop because of calcium lack. The solvent salt substance is higher than 0.3%, the chloride particle is over 0.03%, and the seedling development is influenced by salt.
2. Front
The previous is appropriate for spring wheat, assault, grain and pea.
3. Preparation
With the end goal to expand the yield and increment the interest for phosphorus and potassium manure in the later phase of development, apply 1.5~2 tons of natural compost per 667 square meters previously the developed land (or 100-200 kg of completed natural compost), 5-6 kg of nitrogen manure (urea), phosphoric corrosive. The diamine is 15-18 kg, and 3-5 kg of potassium manure is connected per 667 square meters in Gobi or sand arrive.
4. Put the entire arrive on the ground
The nature of land readiness should achieve the six-character standard. Prior to the sowing, the dirt ought to have adequate base sputum (the dirt water volume is 6%) to 70%; the land is level; the pine: the topsoil is free, there is no center layer and the upper layer is strong; the broken: no substantial earth particles, fine , surface; net: no remaining film, leftover roots, lingering stalks, and so on.; Qi: no deficiency of land, land, and ground.
