Alfalfa has a relatively high demand for some nutrients compared to other commonly grown crops. Each ton of alfalfa dry matter harvested removes about 14 pounds of phosphate (P2O5) and 58 pounds of potash (K2O). This is the nutrient equivalent of pounds of a fertilizer. Each ton of alfalfa also removes the calcium and magnesium. BHC, lindane [almost pure γ BHC] and Thiodan [endosulfan] at 1b. per acre have given effective control of Philaenus leucophthalmus[Philaenus spumarius] (L.) on leguminous forage crops in the United States [cf. R.A.E., A 43 ; 45 ]. Since there is a possibility that the meat or milk of cattle might be contaminated by feeding on treated plants, the persistence of the residues on Cited by: 5. An experiment was conducted to investigate the effects of citric acid residue (CAR) and lactic acid bacteria (LAB) on fermentation quality and aerobic stability of alfalfa silage. Alfalfa was treated as follows: (1) control without additive (CON); (2) LAB (L); (3) 12 g/kg CAR (C); (4) 12 g/kg CAR + LAB (CL) and fermented for 3, 6, 9, 15, 30 and Author: Xuxiong Tao, Sifan Chen, Jie Zhao, Siran Wang, Zhihao Dong, Junfeng Li, Fuxin Sun, Tao Shao. BHC residues were determined in milk samples of cows and buffaloes (Indore, M.P., India), α-, β- and γ-BHC were identified in samples from four different localities using gas chromatography.

alfalfa into row-crop stubble in the spring and after small grain cereals or in forage sorghum and silage stubble in late summer. Late summer seedings are often after winter wheat or spring oats. Alfalfa can be planted no-till into these residues. Most no-till drills can be used effectively to penetrate the standing. following alfalfa is generally not recommended. This is because alfalfa residue can be autotoxic to new alfalfa seedlings and because rotation to an alternative crop can help disrupt alfalfa pest cycles. Variety Selection Based on Plant Traits Alfalfa varieties fall broadly into purple-flowered (Medicago sativa L. ssp. sativa) and yellow-. Soil Types for Alfalfa. And the place to begin with establishing the stand is obviously the soil, because soil fertility and soil conditions play the major role in plant growth and crop yield—and most of all, crop you feed high quality forage to your livestock, they not only will produce more on the same quantity (or less) of feed, but they will also be healthier, and who can.

Experiments were conducted to characterize the allelopathic activity of quackgrass on alfalfa. Both percent germination and seedling length of alfalfa were recorded to evaluate the toxicity of aqueous extracts from rhizomes or shoots of field-grown quackgrass harvested at three stages of . inoculated alfalfa converts atmospheric nitrogen (N) into forms that can be used by subsequent crops. Decomposition of the alfalfa root system typically contributes about lb/acre N to the soil after one year, and an additional 50 lb/acre N in the second and third years. Significantly less N is added in alfalfa-grass mixtures than in pure. Results of the pilot experiment are presented in Figure 1.
