Anaerobic swine lagoon sludge sampling allows operators to determine the nutrient concentration in the sludge through laboratory analysis. This publication provides information about different options for sampling sludge in these lagoons.
Zinc (Zn) deficiency has not been reported under field conditions. Most of the time, the soil will have enough micros to supplement any gaps in the chosen fertilizer plan. To present a more robust set of data, we induced zinc deficiency under controlled greenhouse studies for accurate diagnosis if the problem should arise. In NC State University trials, ornamental tobacco developed a silver cast to the leaves as the initial symptom of zinc deficiency.
This Soybean Nutrient Deficiency Information factsheet describes the symptoms and management of zinc deficiency in soybean production in North Carolina.
In this Brassica carinata (Ethiopian mustard) research update, we highlight the symptoms of zinc deficiency. These images are part of a project by the Southeast Partnership for Advanced Renewables from Carinata (SPARC) to develop a diagnostic series for the identification of nutrient disorders of Carinata. Carinata is an exciting new crop in the Southeast used for a wide variety of primary and secondary agricultural products including cover crops, feedstock, high protein meal, and jet fuel. It is similar in management to canola given both canola and carinata are winter annual Brassica oilseed crops. However, carinata oil is not edible.
