Can be buried in the mud, put in a compost box, or put it in the mud surface. It can improve soil and help plant absorb the nurse. After harvesting, it can be used. The benefits are fast, easy to decompose, and can easily spill the surface of the soil.
Main fertilizer required by plants
Nitrogen fertilizer
When the nitrogen fertilizer is insufficient, the plants become short, the leaves will become yellow, and the fruit is mature early, and the harvest is reduced. Branding crops can be shilted once a week until the symptom disappears. At the same time, other solid nitrogen fertilizers can be added. Or can be used in planning rounds, multiple bean plants, and plus more compost. However, if there is too much nitrogen fertilizer, it will make the stem, the leaves are too lush, but there are small flowers and less fruit, and the crop will become weak, and it is easy to be infected by pests and diseases. Also, there is too much nitrogen, which can increase the content of potassium nitrate in plants, and now there is more and more evidence that nitrate is related to cancer.
Phosphate fertilizer
Insufficient, the leaves are narrow, the points are reduced, and the fruit is reduced, the quality is low, and the leaves and petioles of some crops will become purple. It can be graphic once a week until the symptom disappears. Algae water can stimulate the enzyme of plants, which makes it more effectively absorb phosphorus. In addition, the powder and compost are additional, and the sourctic alkali is adjusted between 6.0-7.0.
Potassium fertilizer
When potassium fertilizer is lacking, the old leaves will be yellow, and then spread to the leaves, then the brown is killed. In addition, the new leaves are dark green, and the elongation inhibits leaflets. The root growth is not good, easy to rot. It can be applied or purple arsena once a week until the symbol disappears. Alternately add wood ash, but you can't have more than once. Long-term, there should be more compost, animal feces, seaweed and other into the mud.
Calcium fertilizer
Insufficient calcium fertilizer, it is easy to produce top corruption in the spring (plants began to rot). It will also make tomato fall flowers, potato plants and stems are not large. Can add lime to improve.
There are 16 elements of health growth to make plants:
Main zein: carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, sulfur
Traceracein: boron, manganese, iron, zinc, copper, molybdenum, chlorine
The main levels are plant composition components, and there are more demands. The micro-quantine is required for biochemical reactions. The above rains, in addition to carbon, hydrogen, oxygen can be absorbed by air and water, and the rest are supplied by the soil.
