Applying fertilizer solutions through irrigation water is not a recent development. The first agricultural use of anhydrous ammonia was through application in irrigation water in the early 1930’s. With the mechanization of irrigation, particularly with the development of center pivot sprinkler systems, new application techniques have been developed for fertilizer and chemical solutions. New words describing these application techniques include fertigation, chemigation, fungigation, herbigation, insectigation, and pestigation.

Soil structure can influence pore space in soil and the ease in which air, water and roots can move through the soil.READ MORE
Taking soil samples can be made easier by lubrication of the probe, especially for wet soils and high clay content soils. The soil can stick to the probe and stop the soil from being released from the probe or make it difficult for the probe to take up soil in the first place. The result of which is a poor sample being taken that does not represent the intended depth from compressing the soil down instead of sliding up into the probe. Research studies performed at different universities have shown no significant effect on soil sample data for macro and micronutrients from lubricating soil probes with WD-40 or cooking spray. Additional investigation performed by Midwest Labs agrees with this.READ MORE
