The Effect of Different Rates and Methods of Application of Alfalfa Green on Turfgrass

The impact of different application rates of AG before and after laying turf grass sod was tested on a plot near WAMCO on heavy clay soils. There were 6 rates with each of the two application methods. Each of these 12 treatments were replicated 4 times. In general, AG was shown to have positive effects on turfgrass growth. The AG applied before the sod was laid showed slight increases in biomass, cover, and colour.

The Evaluation of Natural Source Fertilizers on Kentucky Bluegrass Turf

Alfalfa Green, corn gluten meal, and soybean meal were compared to Milorganite and an unfertilized control in terms of overall effectiveness as fertilizers for KBG turfgrass. The parameters measured were the overall quality of the turfgrass and the clipping yield. Although all three natural source fertilizers had similar impacts on the turfgrass, their performance was equal to that of Milorganite (the industry standard) and did, in fact, have a significant improvement over the unfertilized treatments.

The Effect of Organic Alfalfa Green on Yield and Overall Performance of Different Vegetables

This in-house tested the effect of Alfalfa Green (AG) on seven vegetables: green beans, lettuce, potatoes, pumpkin, onions, beets, and radishes. Each vegetable was tested with three rates of AG- a control treatment (with no AG), a low rate (equivalent of 1 mt/ac) and a high rate (equivalent of 2 mt/ac). Each treatment had two replicates, and parameters measured included percent germination, number of vegetables per plant, average weight of produce, total weight and length of produce, and average weights and lengths of produce. Each vegetable had different results, however an overall improvement over the measured parameters were seen across the garden in the plots that had been treated with AG.

Study of Alfalfa Green at Over the Hill Orchards

To test the effectiveness of Alfalfa Green soil nutrition, a small experiment was designed to measure growth. Alfalfa Green was applied to approximately four acres of sour cherries, consisting of 6 cultivars and approximately 2100 plants. As well as a control treatment, applications equivalent to 1 mt/ac, 2 mt/ac, 3 mt/ac, and 4 mt/ac. It was concluded that the slow release nature of Alfalfa Green did not impact the growth during the season of application, and that a fall application may have more impact.

Alfalfa Green in Composting Systems

Alfalfa Green was compared to common household "Green" ingredients (a.k.a nitrogen sources) such as grass clippings and coffee grounds. The nitrogen sources were layered with vegetable scraps and sawdust in about C:N ratio of about 30:1, then mixed together and watered. Internal temperatures were taken several times a week to monitor microbial activity, and the systems were either watered or drained to maintain an even moisture level. At the end of the 90-day trial period the Alfalfa Green compost system had already finished composting, and the grass clippings and coffee grounds systems were mid-process. The control system had just gotten started composting. In addition, the Alfalfa Green had temperatures consistently higher than the other systems. This may be a result of there being more material in the Alfalfa Green system than the others, making it less susceptible to ambient temperatures. However, this would only account for part of the difference in temperature, and the experiment validates the need for a larger, more in-depth study.
