Potatoes and Kale

First and second earlies = Planted in early February Maincrop = Planted March - April Certified seed potatoes = Seed production category Potatoes for human consumption = Seed production category

Soil pH 5-6 and well drained = Suitable for potato growth Soil with high nitrogen content = Causes potatoes to become watery Soil with added farmyard manure = Holds more water in the soil Soil with large stones removed = Prevents damage to the tubers

Nitrogen = Increased yield but can cause watery potatoes Phosphorus = Increases dry matter and encourages early rooting Potato blight = Caused by an airborne fungus Blackleg = Causes soft rot in tubers

Potato blight = Airborne fungus causing yellow spots turning black Blackleg = Common bacterial disease causing soft rot Fungicide = Helps prevent potato blight Warm weather conditions = Require regular fungicide spraying to prevent blight

Rooster and Kerr pinks = Example of maincrop potatoes with higher yield and flourier texture First and second earlies = Planted in early February General-purpose potatoes = Suitable for human consumption Certified seed potatoes = Used for seed production

Crop rotation = Method of planting different crops in the same area in sequential seasons Certified seed = Seeds that have been inspected and certified to be of high quality and disease-free Potato harvester = Machine used for harvesting potatoes from the field Ventilated insulated store = Storage facility with controlled temperature and airflow for preserving harvested crops

Potato blight = Yellow colouration followed by black stems, spread by seeds Club root = Airborne fungus affecting cruciferous plants, prevented with rotation Red water fever = Anaemia in cattle caused by feeding on kale, damages red blood cells Beetle infestation = Feeding on the roots of plants, prevented with insecticide

Kale catch crops = Fast-growing crops used for crop rotation, mainly for animal feed Maincrops = Potatoes harvested from late September, stored in ventilated insulated stores Fodder crops = Often sown in autumn, used as winter feed, little to no ploughing needed Cruciferae family = Includes crops like kale, requires soil pH of 6-6.5, susceptible to club root

Crop rotation = Prevents diseases and pests, improves soil fertility and structure Use of certified seed = Reduces the risk of introducing diseases and pests to the crop Moderate feeding of kale to livestock = Prevents anaemia in cattle and red water fever Controlled temperature in storage = Reduces sprouting and spoilage of harvested crops

Potato harvester = Machine used for efficiently harvesting potatoes from the field Kale catch crops = Not applicable for this choice Ventilated insulated store = Facility for preserving harvested crops with controlled temperature and airflow Club root = Not applicable for this choice
