LIME ACIDIC SOILS FOR 1999 CROPS

Liming pays in many ways. However, it can do little good at the quarry or at the local fertilizer dealer’s place of business. Aglime can take two or three months to react with the soil and neutralize a part of the soil’s acidity. The smaller the lime particles, the quicker they will react with the soil. So it is time to lime.

Taking good soil samples is the first step. If magnesium is needed, use a finely ground dolomitic lime. If possible, incorporate the lime deep into the soil where the acidity is located. For surface applications to pastures or untilled fields, consider broadcasting about one ton per acre in the fall and again in the spring until the recommended amount is applied to the field.

Some of the benefits from a good and timely liming program include the following:

Aglime and fertilizer are vital inputs for any high yield crop production system. Both are inputs that are totally under management control and should not become yield or profit limiting factors.

Freedom to farm has become a challenge to farm as crop prices and farm profits have taken a nose dive. With a new cropping season comes renewed optimism that 1999 will be better. Two goals, however, should be clearly defined and developed. The first is to strive to lower the unit cost of production of each crop by developing a site-specific lime and nutrient management plan which improves crop use efficiency of each production input. The second is to develop a crop marketing plan with your banker or a marketing specialist that generates a higher return from the increased production. Harvest more profit by lowering the floor with lower unit cost production and raising the ceiling with higher yields of higher value crops.
