Vegetable General Knowledge

The primary purpose of cultivation is to

• control weeds
• control insects
• create a food source
• create habitats for biological species

In gardens, it is suggested that the least practical weed control method is

• hand-pulling
• hoeing
• mechanical cultivation
• chemical herbicides

The most dominant soil type for vegetable production in Florida is

• sandy soils
• clay soils
• loam soils
• hydroponically

One of the major problems with sandy soils is

• leaching of nutrients
• leaching of water
• pesticide resistance
• TMDL

The key to proper use of organic materials as fertilizers comes through

• water testing
• chemical analysis
• soil testing
• knowledge of the nutrient content and the decomposition rate of the material

Decomposition rates of organic materials in warm sandy soils in Florida are

• slow
• fast
• the same as clay soils
• slower then clay soils but faster than loam soils

Usually application rates of organic wastes determined largely by the

• nitrogen content
• phosphorus content
• potassium content
• micronutrient content

The decision to use liquid or dry fertilizer sources should depend largely on

• crop
• cost of material and equipment
• time of year
• growing conditions

In some vegetable crops controlled-release fertilizers ________ production.

• increases
• decreases
• doesn't effect
• provide potential problems for

Overfertilization or placement of fertilizer too close to the seed or root leads to

• soluble salt injury
• nitrogen immunity
• rapid green growth
• "production stunt"
