Cultivation Requirements

Cotton requires soils of medium texture, deep with good water capacity, with organic matter not more than 3% and pH 6.0 - 7.5 with free calcium carbonate not more than 10%. In both very acidic and very alkaline soils, problems arise, especially in alkaline soils, from the binding of Phosphorus.

It performs best in medium-composition soils (sandy, clayey-sandy). The ideal pH for tomato growth ranges between 5.8 – 7.0. It is relatively resistant to soil salinity.

Indicative Basic Fertilization / Recommended Quantities of Nitrogen Phosphorus Potassium:

80 Kg/acre 16- 20 – 0 or 100 Kg/acre 11 -15 -15.

Other details:

It is recommended to add 4 kg/ha (MgO) potassium magnesium sulfate or 4.8 kg/ha (MgO) magnesium sulfate 30 kg/ha.

It thrives in a wide variety of soils, from sandy loam to clayey sandy. However, it prefers light, fertile, deep and well-drained soils. It is considered resistant to lime but on the contrary is sensitive to salinity of the soil and irrigation water. A suitable pH for cultivation is considered between 6.0 and 7.3.

Young trees:

During the year of planting, 30 – 80 g/tree of fertilizer type 15 – 30 – 15 is recommended in the month of May to June for every second watering and with a total amount of up to 150 g/tree/year. In the second year, fertilization is applied in doses with 250 g/seedling of ammonium phosphate. Since the trees are irrigated, we increase the doses of fertilizer by 250 to 500 grams for each tree.

Productive trees:

Phosphorus & potassium fertilization applications are made in November - December. Regarding nitrogen, it can be applied at the end of winter (4 weeks before flowering in ammonia form or 2 weeks before flowering in nitrate form). Another application is recommended in the fall after harvest.

(N) Nitrogen : 1 unit/tree/year

(P) Phosphorus : < 0.5 unit/tree/year

(K) Potassium : If a shortage is observed 7 – 10 kg of potassium sulfate/tree.

The olive tree grows in all soils. However, it performs best in
relatively fertile soils that retain enough moisture. Soils that
"retain water" and make the tree "suffer". It prefers pH 7 – 8,
but it also tolerates slightly acidic soils. It is resistant to
soil salinity and high exchangeable content
sodium.

Application Time:

Phosphorus-potassium fertilizers are applied in the fall or immediately after the fruit is harvested. Nitrogen fertilization in dry olive groves takes place during the period December - February, especially in Eastern Greece and in areas where little rainfall is observed, it is applied at the beginning of this period, while in Western Greece at the end. In irrigated olive groves, nitrogen can be applied in three doses.

1 time in December - February as a basic fertilizer

2 other times later in nitrate form.

Citrus fruits can grow in soils ranging from very light to very heavy. However, they prefer soils of medium mechanical composition, deep & with sufficient moisture. They are plants sensitive to lime. The ideal pH for their cultivation is considered to be between 6 – 7.5. They are crops sensitive to the salinity of the soil and irrigation water. For their cultivation, the electrical conductivity of the soil should be less than 4ms/cm.

Before installing the trees:

It is recommended to add 3-4 tons of digested manure per acre, if the soil contains less than 2% organic matter, as well as to incorporate 20-30 units of phosphorus and 40-60 units of potassium / acre.
