Show News and views from your county agent How to control field bindweed, minimum tillage farming by Blaine Jones USU Extension Agent ment, according to Dr. V. Philip Rasmussen, Extension soil specialist at Utah State University.' Rasmussen has participated in conservation tillage research with wheat growing in both states. This research showed minimum tillage that can work profitably. In some situations we calculated savings of $25 to $30 per acre with yields nearly equal to conventional tillage." He stressed, however, that minimum tillage or conservation tillage requires increased management. Special attention must be given to weed control with herbicides, control of insects and diseases, proper placement of fertilizer and selection of soil and varieties suitable to this type of farming. Proper combinations of these management factors must be found for the crops and conditions in a given area. Rasmussen noted that much has been written in recent years extolling the merits of the farming practices referred to as notill farming and minimum tillage also called conservation tillage. Most articles have discussed the use of such practices, when planting com after corn, : soybeans after soybeans, or rotating com and soybeans. The grower plants the crop in the same field with few or no of planting practical even for large dryland farms. The Extension soil specialist advised approaching minimum tillage cautiously. It is not a practice for the slipshod or reckless farmer. Also, current conservation tillage practices dont give positive results in very coarse, sandy soils or in very fine clay soils. Different conservation tillage practices must be developed for these could injure these plants.
