Profitable crop production largely depends on adequate amounts of available nitrogen. In continuous corn, for example, the dollar return per one dollar invested in nitrogen fertilizer can be as high as eight to one. However, as beneficial and profitable as nitrgoen fertilizer is to crop production, continued inputs of nitrogen fertilizers have increasingly been a concern regarding occurrence of nitrates in ground and surface waters. Consequently, both crop production economics and environmental concerns necessarily demand increasing the judicious and efficient use of nitrogen fertilizers.READ MORE
Modern agriculture demands top yields... and quality yields. Additionally, you demand profitable yields. In satisfying these demands, plant tissue analysis has become a valuable crop production tool. Top quality and profitable yields, unfortunately, don't just happen. Many factors need to be considered... like adequate moisture and fertility, proper plant population, adapted variety, disease and insect resistance and control... the list goes on. One of the more important factors affecting crop yields is the nutrient status of the plant... or the flow of nutrients to plant tissues during the growing season. Nutrient status is an "unseen" factor in plant growth, except when deficiencies become so acute that visual deficiency symptoms appear on the plant.READ MORE
