What is a break crop?
A crop grown to interrupt pest/disease cycles
What is the purpose of applying lime?
To correct soil acidity and increase pH
Explain how integrated pest management reduces reliance on chemicals.
Combines cultural, biological, and chemical controls for sustainability
How does soil type influence planting depth?
Heavy soils require shallower planting to avoid rot
Name one advantage of non-inversion tillage over ploughing.
Reduces soil erosion and preserves organic matter
Name one benefit of including legumes in a rotation.
They fix nitrogen, improving soil fertility
Name the symptom for Nitrogen deficiency in crops
Yellowing of the leaves
What does LERAP relate to in pesticide use?
Buffer zones near watercourses
Why is seed variety selection important for disease resistance?
Different varieties have varying resistance to pathogens
Why is soil type important when choosing seedbed preparation equipment?
Different soils require different tools for optimal tilth
Why are catch crops used in rotations?
To prevent nutrient leaching and improve soil structure
Why is timing of fertiliser application critical?
To match crop growth stages and avoid leaching
Explain why overuse of pesticides can lead to resistance.
Pests adapt genetically, reducing chemical effectiveness
Explain how legislation supports sustainable farming practices.
Reduces pollution, protects biodiversity, and ensures food safety
Explain how incorrect seedbed preparation can affect crop establishment.
Poor seed-soil contact reduces germination and root development
Explain how poor rotation planning can lead to soil-borne disease buildup.
Continuous cropping of same species increases pathogen survival
Explain how incorrect nutrient balance affects crop health and yield.
Deficiencies stunt growth; excess causes toxicity and lodging
