-Protecting or improving soil quality
-Conserving soil nutrients
-Taking care of the environment
-Producing high-quality plants - Answers -Goals of nutrient management include:
-Be 20 to 30 meters wide
-Include fast-growing trees near the stream itself
-Include perennial grasses near the edge of cultivated crops
-Include a spreader berm to slow flow of water from the fields - Answers -In order for a
multi-species riparian buffer strip to do a good job in protecting a stream from sediment
and nutrient loading it should:
Applications as close to crop nutrient need as possible. - Answers -Good manure
management includes:
16.6% - Answers -If the content of potassium in a fertilizer is said to be 20% K2O, then
its content of elemental K is (formula weight K=39.1 g/mol; O=16 g/mol)
-Reducing pollution of soil and water
-Decreasing soil erosion
-Increasing nutrient and water use efficiency - Answers -In intensified agroecosystems,
a goal is to balance food production while:
-It may contain cadmium, chromium or lead
-It contains low nutrient levels, especially of K
-Phosphorus in sludge will have low plant availability
-Transportation costs can be relatively high - Answers -Sewage sludge, the solid by-
product of domestic or industrial wastewater treatment plants, has the following
limitation(s) for use as a nutrient resource:
Nitrogen and Phosphorus - Answers -Diammonium phosphate fertilizer is a good
source of:
-Check out plant shoots and plant roots for normal growth and appearance
-Relate spatial patterns in plant appearance to spatial patterns in soil features
-Develop detailed written records of observations made
take time to discuss the situation with the crop manage. - Answers -In order to be
successful, a soil fertility diagnostician should:
Youngest full-sized leaf at flowering. - Answers -If you wish to get a handle on the
sufficiency of nutrients for your tomato crop, you should sample this plant part at this
