This is a Weed 'Em and Reap Part 1 video clip. Featuring Rob Heater, Stahlbush Island Farms. Corvallis, OR. Audio Text This is what we call an in-row cultivator. It’s built on to a Buffalo cultivator, which is made in the Midwest, I think back in Nebraska. It’s a high-residue, no-till cultivator. We happen to have had a bunch of these that we were using in our crops anyway and decided to make an attachment in here for killing weeds in widely spaced crops, like winter squash and different pumpkins.

The market for organic vegetables is increasing. As conventional farmers transition fields to organics to meet this demand, there is a need for better organic nutrient management guidance, especially for nitrogen (N). Organic N management is more challenging than conventional N management due to a higher level of uncertainty surrounding the N supplying capacity of an organically managed soil as well as the constraints of organic fertilizers (supply, application timing and placement, and uncertainty of release rate and amount). As a result, conventional nutrient management strategies may not be appropriate for organically managed systems. With organic N management there is often a higher risk of excessive nitrate-N loss and higher risk of not achieving economic yield targets.
Several new powdered limestone products that are more finely ground (smaller particle size distribution) than products historically used have become commercially available. A major factor influencing the effectiveness of a liming material is its particle size distribution, with smaller particles reacting more quickly. Because lime efficiency estimates for various particle size fractions were established in the 1950’s, there is a need to evaluate current guidelines to determine if they adequately predict liming efficiency for these new products. The objective of this study was to assess the reactivity of commercially available powdered lime products (both calcitic and dolomitic) and various particle size fractions over a year with the goal of evaluating current OSU lime guidelines.
