Avocado Aftercare

Aftercare: Soil, Filtration and Irrigation
After the scion is cut off from the rootstock, the nutrient an hormone vessel will be opened and the small tree will be planted in a planting basin.  Its important in this stage of the avocado trees live to be treated delicate and have the right mixture of soil, good filtration and the right amount of irrigation.

Soil
The soil must have good drainage properties, because avocado trees roots have a tendency to rot easily with stagnant water, but it also need a lot of water frequently. That is why loose soils is preferred. We will use a sandy loam,  limestone and decomposed granite particle soil for our trees. Avocado trees can grow in both acidic and basic soils, but they prefer a acidic pH of 6-6,5.  The loose soils is also good for the root growing, compacted soils hinder root spreed and which can stunt the tree's growth and contribute to 
root rot.

Filtration
Important nutrients for avocado plants and the filtration we use:
Fertilizer applications require the right balance of minerals because the amount of each mineral in leaves are different. Thus, some minerals are required in greater amounts than others. Very simply, avocados need the right amounts of Nitrogen and Phosphorous for healthy metabolism, Calcium for good structure, Magnesium for good photosynthesis capacity, and Boron, Iron, and Manganese for good health.
The soil we use do have a good amount of each mineral named above. With regular soil and leaf tests for the value of minerals in the plant will help us to know what mineral is needed and what we will give extra to the plant.  It is important to know that some minerals like magnesium can be harmful to the plant when given in to much quantity. We will use a 2:2:1 mix of LAN:MAP:KNO3  filtration applied at 20g/tree, without touching the stem, as a general filtration. When values of other minerals is to low it would be added separately with the right amount.

Irrigation
Irrigation is very important for young trees, but too much water can be more unhealthy  then to little water. Tensiometers will be used to regulate the moist in the soil and will be irrigated according to what the tree needs.  Micros are used to irrigate the soil and spreaders are used to limit the irrigation area. The trees need about 10 liters of water per week and must have a good drainage system so that the roots will not rot.

Soils and Fertilizers

By -
The importance of using the correct soils and fertilizers are of big importance to our company. We are striving towards a greener future and using all bio-degradable products is a good start.   As previously stated we will be propagating:  Avocados using the grafting and air-layering technique (with root stock from seedling) Arum lilies using micro propagation Tomatoes using seeds and a hydroponic system All three of these different techniques use different mediums and fertilizers for different phases of the growth of the plant or seedlings. ·           Avocados: For the Cuttings  ·         Medium : 1:1 - peat moss: perlite (good balance of moisture and drainage)                ·         Fertilizer an Rooting Hormones: IBA (indool botter suur) – Rooting hormone Organic fertilizer – Fertilize on...

Introduction to Tomato proagation

TOMATO PROPAGATION At GrowNurs we propagate our tomato seedlings via Hydroponics.Hydroponics is the process of growing a plant in a liquid with added nutrients but without the presence of soil. Tomatoes grown via hydroponics We use Hydroponics because there  are many advantages using this technique,the biggest of which is a greatly increased rate of growth within our plants.Our plant mature faster and produce up to 30 percent more than the same plant grown in soil. The reason for this is because the plants will not have to work hard to obtain nutrients since there is a continual supply of nutrients available via the solution being pumped through the system.This allows the plant to focus more on growing upstairs instead of expanding the root system downstairs. A hydroponic system uses less water than soil based plants because the system is enclosed,which results in less evaporation.Hydroponics is better for the environment because it reduces waste and pollution from soil...

Arum Lillie's Using Fertilizer and Preparation of Soil

Fertilizer: Although inorganic fertilizers are more readily available we believe in using organic fertilizers. Inorganic fertilizers has the ability to burn the roots, the basal plate as well as the leaves if it comes in direct contact with it, which is another reason why we prefer organic products as it does not have these dramatic negative effects when the concentration of the fertilizer is slightly off. Fertilizers come in granular or liquid form. Granular fertilizers are better because the don't dissolve as quickly, they remain in the soil longer, and the longer the better. Nitrogen (N) is important for preparing soils for bulbs to be able to start their leaf growth. Phosphorus(P) and Potash are good for overall health, resisting disease, root growth and flowering. When adding granular fertilizers, mix with soil ate the bottom of the planting holes. Adding a very diluted liquid fertilizer to the misting system, that regulates the relative humidity in the greenhouse, ...
