BELTSV~LLE 11 SUSTAINABLEAGRICULTURERESEARCHFOR FIELD AND VEGETABLECROPS C. Benjamin Coffman and John R. Teasdale! ABSTRACT The Beltsville sustainable Agriculture Research Program began in th fall of 1992 with the creation of the Field Crops Demonstrati g· n Project. This research/demonstration project was developed t evaluate reduced tillage systems for sustaining productive ~oils on erodible land while minimizing environmental degradation~ Plots ca 0.13 ha are located on a 6 ha site having 2 to 15% Sl!pes. Each treatment follows a 2-yr rotation of cornwheat-soybe n and includes 1) no-tillage with recommended synthetic f rtilizers and herbicides, 2) no-tillage with recommended! synthetic fertilizers and herbicides and a crownvetch (coronilla ~aria L.) living mulch, 3) no-tillage with winter annual cove crops such as hairy vetch (Vicia villosa Roth) before corn (Zea mays L.) and wheat (Triticum aestivum L) before soybean [GI cine max (L.) Merr.], with reduced fertilizer and herbicide ipputs, and 4) chisel plowed organic system using animal and plan~ manures and mechanical weed management. In 199· the sustainable Vegetable Production Research Project was established to develop management practices for summer and all vegetables. Conventional practices including synthetic f. trtiiizers and plastic mulches are compared with cover crops and r~duced synthetic inputs. Cover crops for summer vegetables ~'nclude hairy vetch, crimson clover (Trifolium incarnatum .), and rye (Secale cereale L.), with forage soybean and German illet [Setaria italica (L.)] cover crops for winter vegetables.: The Fa~ming systems Project was established on 16 ha at Beltsville 1n 1993 with an objective to investigate the effects of 10ng-te~ alternative crop production systems on biological, environment 1, and economic aspects of field crop production. After 3-yr . f uniformity trials field plots were established in 1996. A shprt-term goal is to investigate the transition effect of change.f~om conventional methods to farming systems that differ in crop diversity, weed management, and nutrient source strategies. Systems presently being studied include cash grain rotations w.'th varying length and intensity using synthetic fertilizers[, fresh and composted manures, and green manure. Compon~nt projects include 1) studies of the feasibility of using farm'lmuniciPle, and industrial byproducts as soil amendments, 2) in-depth investigations of composting variables, and 3) comp rison of an ARS developed strain of Bradyrhizobium with conven~ional strains of rhizobia for soybean production.
