Soil sulfur is not a very well known element, but it is part of the macronutrients. Sulfur or S, is absorbed in the same amounts as phosphorus. Uptake of S by grasses is about 10 kg/ha, leguminous crops 25-30 kg/ha and cabbage about 40-45 kg/ha. The table below compares sulfur [...]
Soil calcium can be a mystery as most growers focus on nitrogen, potassium and phosphorus. If you scan literature, scientists get very involved in detail and confusing for the average non post graduate farmer. This is a simple yet quick cheat sheet on soil calcium that will quickly give you [...]
Climate requirements of carrots Carrots is a cold weather crop. The ideal growing season is from early autumn to late spring. Carrots can be grown throughout the year if summers are not too hot like the lowveld in South Africa. Although heavy frost damage leaves, it does not affect the [...]
Carrot fertilizer requirements can be calculated if you know your soil type and have a good idea of the yield potential of your land and climate. These are basic norms and your specific microclimate and variety can have an influence on the total amount applied. These norms do not take [...]
Scientific application of a spray program ensures its effectiveness. All chemicals must be applied at the right place (target) and the right time and in the right way. Pesticides and fungicides are dangerous chemicals, they are designed to kill pests and diseases, but they can also kill humans if not [...]

Beetroot fertilizer requirements can be calculated if you know your soil type and have a good idea of the yield potential of your land and climate. These are basic norms and your specific microclimate and variety can have an influence on the total amount applied. These norms do not take [...]
When susceptible crop plantings follow at close intervals i.e. within 12 months or less, beet cyst nematode builds up in the soil to damaging population concentrations. High populations may reduce the yield by 20-40%. The beet cyst nematode was found in vegetable lands around cities such as Johannesburg, Pretoria, Cape [...]
The most well known beetroot varieties or cultivars are discussed here. When starting it is advisable to use at least 2-3 different varieties in a test field to assess which variety suits your growing conditions the best. Always keep on doing trials. Don't plant a variety just in one time of the year. Your climate might be more moderate than you think.
Harvesting beetroot Beetroots is harvested in phases. Initially when the bulbs are 25-40mm in diameter. Size will vary according to variety planted and time of season. This is the first harvest and is merely a thinning out process. The second and final harvest is when the bulbs are 50-75mm in [...]
