Your goal as a greenhouse grower is to maintain a stable pH over the life of the crop. This is not an easy task since many factors can affect pH in the growing substrate. The pH can go up or down within several weeks of the crop cycle and if you wait for deficiency or toxicity symptoms to develop, you have already compromised the health of the crop and you r profits. Knowing all factors involved is the first step to managing the substrate pH.

When the peach tree moves into its bearing years a shift in emphasis from exclusive attention to vegetative development for building a tree structure to maintaining a balance enough vegetative growth to promote adequate fruiting wood and return bloom for the following season’s fruit crop and managing the current season’s fruit crop.

Hophornbeam copperleaf has become an increasing problem in agricultural fields throughout Georgia. It can occur at densities that have the potential to reduce yields and influence harvest efficiency. Hophornbeam copperleaf is also known as three-seeded mercury.

Turfgrass stands can be injured and damaged by biotic (living) and abiotic (non-living) agents. Most abiotic diseases cause generalized symptoms such as wilting, yellowing, thinning and the development of smaller than normal grass blades, limited root growth or slow growth. Based solely on symptoms, however, determining whether the condition is caused by a biotic or an abiotic agent can be challenging. In many cases, a proper diagnosis of abiotic diseases requires thorough examination of the site, knowledge of relevant past and present environmental conditions, in-depth knowledge of plant species biology, site management history, and an orderly series of tests to determine possible causes.
