Seed sowing and seedling.

We buy vegetable seeds in garden stores. We are sure then, that they are checked in terms of germination for a given year. If we have seeds from previous years or we obtained them from our own collection, …

Calculations of the volume of earth masses using the square mesh method
To calculate the volume of earth masses by the square mesh method, you need a situational and highness plan that is the basis for the development of the project, made by the square mesh method. A height plan made on the square mesh with the layer of existing shape. Squares on the....
Dimensions of garden benches
Dimensions of garden benches. Garden benches for adults have the following dimensions: Bench without support - seat height 35 - 45 cm, width - 40-50 cm, Bench with backrest - seat height 35-40 cm, width 40-50 cm, Height of the backrest 35-40 cm. Benches for children should be adapted to their knowledge..
Calculation of the volume of earth masses by cross -section
Calculating the volume of earth masses by cross -sections is possible, If you have a technical and robot project, on which existing layers and designed layers are deleted. Calculation of this method is carried out in a sten, that on the plan in characteristic places of earthworks you....
Gravel and crushed surfaces part 1
Gravel and crushed surfaces can be thickness 6 - 20 cm, depending on the permeability of the substrate and the expected load. Surfaces on loose and permeable soils may be a small thickness, Gravel-plastic surface on a permeable 1 - thick gravel or crushing, 2...
Mechanical properties of land
Mechanical properties of land. The most important mechanical properties of land include: load -bearing capacity, internal friction and coherence. The load capacity is called soil ability to carry loads. It is expressed by a load -like load ratio (N/m2). This is the maximum load, what not....
Improved ground surfaces - stabilized part 1
Land, from which the surfaces are made, can be improved by increasing their coherence, reduction of absorbability and increasing load strength. This is achieved by adding various binders, which bind small particles of land. Cement is used as a binder, lime and various biological binders...
Strengthening the edges of the tanks - fascination
Strengthening the edges of natural tanks can be done in different ways and using different materials. Different considerations determine the choice of method and material, such as. Type and purpose of the tank, use, Designed type of DNA strengthening, Availability of materials, economic considerations...
Gravel and crushed surfaces part 2
The execution of the gravel or crushed surface is to dig the road bearing, securing its edges by setting the curb or laying retaining stones as well as the spread and leveling of the aggregate layer and it. In multi-layer surfaces, each layer should be rolled..
Calculations of the volume of earth masses by the method of layers
To calculate the volume of earth masses, you need to use a layer plan with an existing and designed system. One of the two foundations. Such a plane is located at the level of each layer..
The physical properties of the ground
For design, calculating and performing works in the field of shaping surface and earthworks is necessary to know the basic, land properties. The physical properties include: apparent density, grainness, porosity and humidity. Knowing the apparent density is important in....
