A lot of farmers don't make it. It's not water, it's fertilizer. – forty pounds of urea-based fat, a few pounds of urea-based fat, and a few pounds of platinum, three or five kilos less, and the three fertilisations below are broken。
Kee-foo's one-time job
When the floor rises, the bottom is applied once, with 1,000 to 1,500 kg of rotting organic fertilizer per acre, plus 30 kg of calcium phosphate, six kg of urea, and two kg of zinc sulphate, all of which are applied in 15 cm deep ditches, where the fertilizer is put on the bottom of the ditch and the soil is covered. Organic fertilizer must be completely decomposed, with unburned manure burning its roots and dying of direct yellow leaves。
The urea is only 15% of the total of 40 pounds of urea. Don't think urea is cheap enough. Phosphorus and zinc are the root of this. Calcium perphosphate and zinc sulphate mixed with organic fertilizer can reduce nitrogen volatilisation, with utilization rates nearly 20 per cent higher than single urea and savings。
It's before the sixth leaf
Acreage is used for 10 kg of urea, or one quarter of the total, when maize grows to six to seven leaves. Don't wait for the leaves to come to nine, the roots and partitions are too late to keep up, the whole plant is weak, and there's no way to make up for it. Six leaves are the first time to start, seven leaves are the last line。
The urea particles are spread around the plant and remain three to four fingers wide from the root, and cannot be stacked directly at the root, either in the morning of the day or when the soil is dryed out after the rain. After five days without rain and drying the surface, 300 pounds of water must be poured away, otherwise the local concentration is too high to burn the seedlings directly, the light leaves are focused and the whole tree is heavy。
Fatten is the key to food production
About 60 days after planting, the leaves are fertilized between 11 and 12, and the remaining 24 kg of urea added to 10 kg of potassium chloride is fully applied at once. This is the largest of three strokes, accounting for 60 per cent of the total urea, with a long stasis, a split ear, a small trophic end of the ear, and a loss of two levels of production。
Direct leaves of the seeding date cannot be remembered, 11 films starting to end in 12 pieces and ending in the next window period. Potassium chloride is not in the same position as the urea pile, spread in two circles in more than a dozen centimetres, full of potassium tubles, a nitrogen tubing tubing plume, staggered to allow the root to be absorbed in batches, and the utilization factor is greater than the mix。
I don't want you to know that
The urea is spread throughout the circle and three to four fingers from the root. It is tantamount to stacking high concentrations of salt directly on the stubble, with yellow hair on the tip of the light leaf, with the whole tree strangling, year after year, and making it more expensive to return to work。
And when it is done, do not turn over the earth, and step on the surface with your feet, so that the particles may be attached to it. Fertilizers are best before rain, which naturally washes them into the earth; water must be distributed during the dry days, 300 to 400 pounds per acre, and urea water concentrations are within 2 per cent. The higher concentration is the same as the unspoiled。
Let's see what we can do
Before applying fertilizers, three things are seen: once the weather is forecasted, no more than three days later, no more than a medium rain, no more fat, no more than a puddle, no more than a day's watering, no more than a puddle, no less than a urea, no more than two pounds of urea for a plant。
Low-lying fields have 10 to 20 kg of base urea-proof roots, poor sand soil, and a double application is better than a single application. In more than three years of maize, two kilograms of bobby can be added to the base fat, which can significantly reduce the incidence of oscillosis, saves later use of the drug and saves money。
It's only because we're fatter
The whole crop requires between 700 and 900 millimeters of water for long periods of life, and water peaks to the point where irrigation cannot keep up with any more fattening. Conditional plots are drip-drived, urea is dissolved and applied with drips, twice as high as the evaporation rate, and the saving of fat and labour can be increased by 350 pounds in an acre。
In the absence of irrigation conditions, two rows of open land are left in the rows as drains and water is protected while the rain is stored. One week after the application, the color changes from yellow to green, indicating that the fat is working, or if the yellow is enough, the water is not full. Don't wait for the pecker to find out the problem。
