Pb1637 Fertilizers And Their Use, The University Of Tennessee Agricultural Extension Service

Field & Commercial Crops

An understanding of soil chemical properties is important because of their effect on nutrient availability to plants. Also, these properties may usually be favorably altered with the use of lime and/or fertilizer materials. Many plants need 18 elements (see Table 1) for normal growth and completion of their life cycle. These elements are called the essential plant nutrients. Soil amendments containing the essential plant nutrients or having the effect of favorably changing the soil chemistry have been developed and used to enhance plant nutrition. These amendments are our lime and fertilizer materials.

With the development of these modern lime and …

Sp548 Fertilizing Landscape Trees, The University Of Tennessee Agricultural Extension Service

Forestry, Trees, and Timber

Trees in residential and commercial landscape plantings are often fertilized to keep them healthy and attractive. Over-fertilization is common, causing excessive growth, especially on young nursery stock. Trees growing in lawn areas usually receive some nutrients when the turfgrass is fertilized. This is usually sufficient to maintain most trees in fertile soil. However, fertilization may be needed on altered soils where unconsolidated fill material has been added or the topsoil has been removed. Managed urban areas where fallen leaves are removed may also require a fertilization regime to enrich soil and replenish nutrients.

Fertilizer (plant nutrition) is no substitute for …

Pb1038 Fertilization & Management, The University Of Tennessee Agricultural Extension Service

Home Garden, Lawn, and Landscape

Fertilization and liming practices based upon a soil test help ensure the most cost efficient and environmentally sound development and maintenance of lawns. A soil test is especially critical when soils test low in pH, phosphorus or potassium. A properly fertilized and limed lawn is usually greener, more vigorous, less weedy and more attractive than a poorly fertilized lawn or one suffering from the effects of low soil pH (soil pH is a measure of the soil’s acid content).

The primary nutrients (nitrogen, phosphorus and potassium) must be added to most lawns, since soils in Tennessee seldom furnish adequate supplies. …

Pb1616-Plant Nutrition And Fertilizers For Greenhouse Production, The University Of Tennessee Agricultural Extension Service

Commercial Horticulture

This publication is one of three in a series that covers the basics of developing a nutritional program for producing container-grown plants in greenhouses. A complete nutrition program encompasses the fertilizers, media and water used. The first section in Plant Nutrition and Fertilizers for Greenhouse Production develops background information about plant nutrition that growers need to understand before discussing which fertilizers to use. The second section covers the range of fertilizers that growers can choose from.

The second publication in the series, Irrigation Water Quality for Greenhouse Production (PB 1617), examines the effect of water quality on a greenhouse nutritional …
