If you could increase your yields and your markets demanded more produce, would you spend money on soil amendments? Derek Christianson of Brix Bounty Farm in Dartmouth, MA has long recommended farmers pay attention to soil micronutrients. He said soil amendments or foliar sprays are easy to justify with increased yields in healthier plants.
Christianson described the benefits of improving micronutrient availability in an Advanced Growers Workshop for the Northeast Organic Farming Association of RI (NOFA/RI). His program explored the nutritional needs of different crop families, key minerals needed to support healthy growth and the role of fertility management in achieving optimum yields. Christianson covered five crops, their fertility needs, cost and expense considerations and growing season management. Crops included beets, onions, spring cabbage, tomatoes and winter squash.
Thorough, accurate soil tests are critical for any grower. Site analysis and test results help determine ideal crops for a particular site as well as appropriate amendments. [Read more here.]
