Soil tillage at both the garden and field scale should take place only within the soil moisture range of 50–75% of field capacity (see Appendix 1, Estimating Soil Moisture by Feel, and Unit 1.5). Whether using a spade and fork, or tractor-drawn tillage tools, tillage executed at soil moisture levels higher than 75% of field capacity can increase soil compaction, degrade soil structure, increase surface crusting, and increase erosion potential. Soil tillage undertaken when soil moisture is below 50% of field capacity may pulverize soil aggregates, resulting in poor soil structure and increasing the risk of soil erosion due to…

Soil erosion is the natural process of detachment and movement of surface soil by water or wind, and has occurred simultaneously with soil formation on the Earth for millennia. In natural ecosystems the formation of soil from decomposing plant and animal matter occurs in balance with the rate of erosion, maintaining overall soil health and fertility and preventing a net loss of topsoil.

Physical properties of soil are divided into texture and structure. Soil texture is a physical measurement of the percentage of sand, silt, and clay particles in a soil (as determined by grain size, with sandy soils being the largest and clay the smallest). It is a given, and cannot be altered (see more in Unit 2.1, Soil Physical Properties). Sandy soils usually feature low nutrient- and water-holding capacity and an associated lower organic matter content. On the plus side, sandy soils drain well, warm quickly, and allow early cultivation and planting in the spring. Clay soils are the opposite: they…
FIT is a member of the College Consortium for International Study, which includes approximately 100 colleges across the United States that offer study abroad programs. Under the auspices of the consortium and FIT, fifth-, sixth-, or seventh-semester students admitted to the Bachelor of Science degree programs can study at institutions across the globe. Advertising and Marketing Communications BS degree students as well as AAS degree Fine Arts students may spend a fall or spring semester at the Scuola Lorenzo De’Medici in Florence, Italy.

The term “biota” is used throughout this text in lieu of “flora” as a general reference to bacteria. Flora refers to plant life. “Bacterial flora” dates back to the time when it was believed that bacteria were primitive plants. Since bacteria are not plants, “bacterial biota or microbiota” is preferred to flora. The major genera of bacteria, yeasts, and molds that are found in these products before spoilage are listed in Tables 4–1 and 4–2. In general, the biota is reflective of the slaughtering and processing environments as noted above, with Gram-negative bacteria being predominant. Among Gram-positives, the enterococci are…
The Egyptians used a surprisingly large number of makeup and skin care products. Rouge colored their lips and cheeks, while dyes and paints hued their body and facial skin. There is enough evidence to show that the Egyptians even colored their hair. Perhaps best known of all is their extravagant use of kohl to accentuate the eyes. This dark colored powder was made with many different naturally occurring substances that gave different hues and different textures. Some of these are crushed antimony, lead, copper, burnt almonds, ash, malachite, copper ore, ochre and many others. Both the upper and lower lids…
The Center for Agroecology and Sustainable Food Systems (CASFS, the Center) is a research, education, and public service unit of the Division of Social Sciences at the University of California, Santa Cruz, dedicated to increasing ecological sustainability and social justice in the food and agriculture system. Center research and education efforts seek to increase understanding of the social, economic, political, and ethical foundations of agricultural sustainability; to establish the ecological and agronomic basis for sustainable production systems; and to demonstrate and facilitate the use of information critical to the adoption of sustainable food and agriculture systems. The Center’s work covers…
To sustain high crop productivity and crop quality in food and fiber production (not maximum yields, which typically require excessive nutrient inputs to achieve) a) Crop productivity, crop quality, and the economic viability of a given farming operation 2. To minimize environmental quality and human health risks associated with agricultural production a) Important steps in minimizing human health risks and on- and off-farm impacts i. Avoid the use of all synthetically compounded materials (e.g., fertilizers and pest control agents, etc.) known to have an associated environmental quality or human health risk ii. Avoid creating non-point source (NPS) pollution through surface…
Cultivation is a purposefully broader concept than simply digging or tilling the soil—cultivation involves an array of tools, materials and methods that, when properly combined, promote and maintain optimum soil health and good tilth, a composite term for the overall physical characteristics of a soil (texture, structure, permeability, consistency, drainage, and water-holding capacity). In short, tilth equals the workability of a soil in relationship to its ability to grow plants. This unit introduces students to the tools, techniques, and rationale behind traditional French-intensive organic gardening and mechanized, field-scale soil cultivation. Beginning with the concepts of soil cultivation and tillage, students…
Full-time students who are New York State residents may be eligible for a TAP grant ranging from $500 to full tuition per year. New York State residents who are registered for 6–11 credits in a degree program may be eligible for Aid for Part-Time Students (APTS) or Part-Time TAP. For more information, visit fitnyc.edu/financialaid or hesc.com. Only courses required for the student’s current degree program will count toward TAP enrollment. Regulations require that full-time students receiving state awards complete a minimum number of credits each term in a registered or otherwise approved program with a minimum GPA, and accumulate enough…
