Can you apply too much potash? Yes, applying too much potash can lead to nutrient imbalances, which can negatively impact crop health and yield.

How much CO2 does corn remove? Corn removes carbon dioxide (CO2) from the atmosphere during photosynthesis. However, the specific amount varies based on factors like growth stage, weather, and location. On average, a hectare of corn can remove several tons of CO2 over its growing season.

What is the phosphorus removal rate of corn? Corn typically removes about 0.2-0.4 pounds of phosphorus (P) per bushel of grain produced.

Is corn silage better than hay? The choice between corn silage and hay depends on factors such as livestock nutrition needs, availability, and farm management practices. Both have their advantages and disadvantages.

Is silage more nutritious than hay? Silage and hay have different nutritional profiles. Silage tends to retain more nutrients, but the specific nutritional content depends on factors like crop type and harvesting method.

How do you calculate removal capacity? Removal capacity is calculated by multiplying the nutrient removal rate (e.g., pounds of N, P, K per bushel or ton) by the crop yield (bushels or tons per acre).

What is the difference between CBOD and BOD5? CBOD (Carbonaceous Biochemical Oxygen Demand) and BOD5 (Biochemical Oxygen Demand over 5 days) are both measures of organic matter pollution in water. The key difference is the duration of the test. BOD5 measures the oxygen demand over a 5-day period, while CBOD measures the oxygen demand primarily from carbonaceous organic matter over a shorter period.

What is the range of BOD percent removal considered efficient? Efficient BOD removal is typically considered to be 90% or higher, indicating effective wastewater treatment.

What is the formula for nutrient efficiency? Nutrient efficiency can be calculated as the ratio of nutrient uptake by plants to the amount of nutrient applied:

Nutrient Efficiency (%) = (Nutrient Uptake / Nutrient Applied) x 100

What is the nutritional value of corn? Corn is a good source of carbohydrates, fiber, vitamins (especially B vitamins), and minerals (especially potassium and magnesium). Its nutritional value can vary based on factors like variety and preparation.
