Step 1
Zero grazing and strip grazing
Answer
Zero grazing refers to a system where animals are kept indoors or in a confined area, and feed is brought to them directly. This system minimizes the animals' movement and is usually resource-efficient as it controls feed consumption.
In contrast, strip grazing allows animals access to a fresh strip of grass or forage crop daily. This method relies on movable fencing and promotes grass growth by preventing overgrazing in one area.
Step 2
Contact fungicides and systemic fungicides
Answer
Contact fungicides are applied to the surface of the plant and kill fungi on contact. They act quickly but require thorough coverage to be effective, meaning their application must be precise and extensive.
Systemic fungicides, however, are absorbed into the plant and translocated to all parts. They act from within the plant, offering protection even after rain, although they usually require less coverage during application.
Step 3
First early potatoes and maincrop potatoes
Answer
First early potatoes are typically harvested immature in June and are sown in early spring. They are characterized by a lower yield but are produced earlier in the season.
Maincrop potatoes, on the other hand, are sown later in the spring and are harvested fully mature in autumn. They generally yield higher quantities and are grown in various conditions, often offering better storage capabilities.
