Abstract: Continuous no-till (NT) has numerous benefits, including improved soil aggregate stability in the surface soil and increased rate of water infiltration, but accumulation of soil P at the soil surface with NT can increase P concentration in runoff. We hypothesized that occasional one-time tillage of NT land, conducted once in 10 or more years, can reduce P runoff and improve crop yields without reducing soil aggre- gation or increasing runoff. Research was conducted in long-term NT fields under rainfed corn (Zea mays (L.)) or sorghum (Sorghum bicolor (L.) Moench.) rotated with soybeans (Glycine max (L.) Merr.) at two locations in eastern Nebraska. Tillage treatments were applied in the spring or fall and included continuous NT, tandem disk (disk), chisel with 10-cm-wide twisted shanks, moldboard plow (MP), and mini-moldboard plow (miniMP). Subplots had either 0 or 87.4 kg P ha21 applied as composted feedlot manure before tillage. Yield and yield components were measured for 2 and 3 yr after the spring and fall one-time tillage, respectively. In Year 2 or 3 after till- age, soil sorptivity, field-saturated infiltration rate, runoff volume, runoff P loss, and soil aggregate stability were determined. Yield was not affected by the tillage 3 compost interaction, but was increased by compost application at one location and sorghum yield was af- fected by tillage treatments at the second location. Grain yield was never significantly more or less with one-time tillage as compared with NT. Soil aggregate stability was not affected by tillage treatments. Sorptivity and infiltration were increased with MP tillage compared with NTat one location but reduced at the other. One-time MP tillage reduced dissolved P loss at both locations and total phosphorus (TP) loss at one location. The benefit of one-time MP tillage in terms of reduced dissolved reactive P loss in runoff was positive with no nega- tive effect on soil aggregate stability but no gain in yield.

En 2010, luego de un proceso liderado por la Comisión Honoraria del Plan Citrícola (CHNPC), INIA, INASE, DGSA y el propio Ministerio de Ganadería, Agricultura y Pesca (MGAP), se firmó un convenio interinstitucional para desarrollar un Programa Nacional de Saneamiento y Certificación de Cítricos (PNSCC). En el presente trabajo se presentan los avances y logros alcanzados para poner a disposición del Sector citrícola nacional, yemas de variedades y semillas de portainjertos certificadas libres de virus. |
