Natural Farming Research Note Now Available!
Between 2017 and 2018, a trial was conducted comparing IMO, EM, mulch, and no mulch on a raised bed system on the ECHO Florida campus. Each of these main treatments was evaluated with and without NPK fertilizer in a split-plot, randomized complete block design. Less cotton was decomposed in the soil of the control treatment than soil of the EM soil drench treatment (P=0.0542) suggesting lower rates of microbial activity. Fertilized split treatments produced more grams of edible product than unfertilized split treatments (P<0.05). This study was conducted in a sandy soil with low organic matter. IMO or EM products may need to be “stepped up” to more stable carbon sources such as bran, compost, or manure before being utilized in soils low in organic matter.
