Poor harvest – mistakes which can be avoided
Poor weather is not the only cause of low yield. Agricultural manufacturers are also responsible for the quantity of harvested foodstuffs. Fortunately, there are foolproof ways to eliminate mistakes leading to disappointing yield. Here are the mistakes connected with cereal sowing and cultivation, which may be eliminated:
Wrong soil pH
Devoting too little attention to adequate chemical balance in the soil is a very common mistake made by farmers. If the soil is deficient in limestone, it becomes acidic. Despite intensive fertilization, plants are unable to absorb nutrients in such an environment. In an acidic environment, compounds are created which are not soluble in water, and may not be absorbed by the plants.
Wrong kind of fertilization
Agricultural manufacturers reduce the yield by excessive use of nitrogen-based fertilizers and by neglecting the need to use lime fertilizers. The use plants make of the minerals in the soil depends to a large extent on the manner and timing of applying the fertilizer. An excessive dosage of fertilizer may result in turning the soil acidic. The nitrogen from the fertilizer may also be flushed away together with rainwater. In each case, the nitrogen is not absorbed by the plants in the appropriate way.
Bad choice of crops
Driven by economic motivation, some farmers decide to sow plants which are expected to fetch a good price after the harvest. However, we need to remember that not all kinds of plants may bring a good yield on a given kind of soil. Let us take wheat – it may be very profitable, but what difference does it make if it produces a scant yield on our farm? In order to make a good choice of the kind of cereal cultivated on the farm, the producer may to refer to the List of Recommended Crops, which gives the kinds of plants providing the highest yields in their region of Poland.
If the sowing is postponed, the air becomes colder and colder, which has a negative impact on the growth and development of cereals, in the end reducing the yield. Grains which are sown in late autumn, especially if they are not covered with earth, are prone to be damaged by below zero temperatures. Also, we should keep in mind the fact that some types of cereals are absolutely inappropriate for late sowing. Those types have poor resistance to frost.
