"If a healthy soil is full of death, it is also full of life:
worms, fungi, microorganisms of all kinds ...
Given only the health of the soil, nothing that dies is dead for very long."
- Wendell Berry, The Unsettling of America, 1977

From easily visible earthworms to microscopic bacteria, discover valuable information on the roles and interactions of the soil's flora and fauna. See how soil biology relates to soil horizons, porosity, water holding capacity and other physical properties of soil.
While soil fertility is often measured by a soil's chemical, mineral and organic matter content, new research is presented on how the many species of mesofauna can be extracted from the soil and then used as indicators of soil fertility. Examine soil pests as well as beneficial life forms found in the soil. Also see human attitudes towards soil organisms and learn how opinions can develop which are not always based on science. Clear narration, effective use of graphics and fascinating microphotography bring into focus the many life forms in the soil of our farms and landscapes. 24 minutes.
This in-depth video series presents the interdisciplinary topics of fertilizers and soil fertility. Soil science, chemistry, botany, physics, economics and mathematics all play a role in the strategic use of fertilizers.
This four-part series provides a wealth of information on the essential topic of soil fertility. The relationships between soil, plants and nutrients are explained along with many practical techniques used to accurately, and economically, apply fertilizers. The programs are designed with both instructors and students in mind.
Topics are arranged in a logical manner giving instructors the flexibility to design their lesson plans according to their own teaching style. Throughout the video program, instructors will find many opportunities to incorporate their own information and present the themes and ideas at their own pace. Technical terms are easy to read on any TV screen and animated graphics help students quickly grasp and retain the information.
This series demonstrates the use of fertilizers in agriculture, horticulture and the landscape industry. The intended audience includes high school and university students studying soil science, horticulture, agriculture, botany and environmental science. The content of this series is partly based on agricultural core curriculum standards. |
In part two (22 minutes) students will delve into and nutrient availability, nutrient deficiencies and the diagnosis of plant problems. The various factors effecting nutrient availability and nutrient absorption are presented. Students will see nutrient- deficiency symptoms and learn how to distinguish between nutrient deficiencies and other plant problems. $119.00
The third tape in this series (23 minutes) demonstrates how to test soil fertility. Students will see how to properly collect soil samples for laboratory analysis. The results from the soil analysis explained in detail, along with the recommendations given by the soil laboratory. This program also defines the terms used in the fertilizer industry and explains the information found on fertilizer labels. Students will see a commercial fertilizer distributor as well as a variety of different fertilizer forms and application methods. Both organic and inorganic fertilizers are presented.
Part Four, the final tape in this series (22 minutes), shows how to develop a cost-effective fertilization program. The program goes step-by-step through various fertilizer calculations for agriculture, horticulture and landscape applications. Examples of price comparisons are calculated, as well as fertilizer application rates for turf and for organic materials. Fertilizer injectors are demonstrated as students learn how to set up and solve equations needed for designing a constant-feed program. This section enhances students problem-solving skills and critical thinking abilities.
$79.95 How Chemicals Moves though Soil DVD Ideal for viewers concerned with water quality and other groundwater issues. This video looks closely at how chemicals move through various soil types and conditions, especially chemicals carried by water. Concepts presented include chemical transport (diffusion, convection and hydrodynamic dispersion) ... Chemical interactions (adsorption, absorption, desorption, cation exchange) ... and chemical transformations (hydrolysis, photolysis, oxidation and reduction) as they occur in soil. Computer models actively demonstrate comparisons of different chemicals as they move through soil. Excellent for students and people working with agriculture, golf courses, parks, landscaping, athletic fields, wetlands or landfills.

Introduction to Land Judging DVD $119.00 Fungi: Decomposers and Parasites DVD
Our Fungi DVD begins by describing hyphae-the filamentous, thread-like fungal cells that intertwine to form interwoven masses called mycelium which are usually only visible when differentiated into sexual structures such as mushrooms, puffballs, and powdery molds. How fungi obtain nutrients either through parasitic or mutualistic relationships or decomposing dead bodies is examined before looking at their economic, ecological, and health impacts. The major divisions of fungi are then examined and some of the unique adaptations found in kingdom Fungi are discussed.
