The overstructure mix is formulated to nourish and grow nearly any sort of planting material where there lies a structural limitation regarding weight, and a light weight mix which provides soil nutrients and maximizes drainage is therefore necessary.
Material composition consists of an Aguinaga Green nutrient package carefully selected and blended for quality and performance in order to satisfy general N/P/K requirements. This blend is married to a combination of pumice, sand, and 0-1/4 fir bark. Pumice increases volume at a low weight, and sand assure drainage. Firbark assures adequate nutrient and moisture retention.
There are premium variations of overstructure mixes utilizing alternate materials, and dependent upon application. Each is pH balanced with an emphasis on E.C. (electrical conductivity – which is a measurement of salts as it would relate to plant and soil requirements).
Overstructure mixes are generally two stage, where the top layer consists of a composition growth medium of sand, pumice, organic material, and nutrients, and the lower player consists of a composition drainage medium. More recently a single layer has been incorporated which simplifies installation as well as insures growth medium throughout the profile. This encourages further root growth into the lower planter drainage area.

Planting a new lawn
A sometimes overlooked aspect of planting or maintaining a lawn lies in not taking into account the nature of the soil the lawn is to be planted in.
There are three basic types of soil; clay-laden - consisting mainly of very fine particles that retain water nd have a tendency to stick together or ball-up if you try to squeeze a handful, sandy soil - made of much more grainy particles and thaat have a greater difficulty holding moisture, as it tends to percolate right through this material, and loam - which is a combination of both sand and clay.
Once you have a sample of the soil in your planting area, it is wise to get a soil analysis which will tell you the pH (acidity or alkaline nature of the soil) and the amount of nitrogen, phosphorus and other organic material present - and - how far off the mark your soil is to an ideal composition and texture that will best promote growth.
Soil amendments are materials such as humus, peat moss, shaved bark, compost, lime, gypsum, and sulphur, and must be added only as necessary dependent on the specifics and/or deficiencies of a given soil. They can result in improved aeration, drainage and root penetration, and a healthy microbial environment that will promote the growth and well being of your lawn.
Contact Aguinaga for further information in planning your next lawn - or any other project requiring mulches or soil reparation.

Using compost with gypsum improves clay soils
Gypsum, otherwise known as calcium sulfate, can be used to amend clay-based soil and also to improve soils with high concentrations of sodium.
Amending clay-based soils with gypsum leads to healthier and more productive plant growth. Gypsum also improves soil structure and infiltration rates when there are high concentrations of sodium.
Aguinaga’s General Purpose Soil Amendment 1 (GPS 1) is one of Aguinaga’s special blends. It consists of general purpose mulch, recycled green matter, turf plus, and gypsum. The blending of these products has brought forth an excellent balanced planting soil amendment that has a multiplicity of uses throughout the garden area, regardless of soil texture. Sandy soil will begin to retain moisture and clay soil will have improved drainage and aeration.
The addition of turf plus improves the nutrient levels in the product and adds organic nitrogen for long term, slow-release microbial activity. The improved levels of soil bacteria greatly enhance root development and stimulate plant growth. GPS 1 particle size is 0 to 1/2 inch. It is nitrolized and stabilized and fully composted.

pH and Compost
What is pH?
pH Factor means potential Hydrogen and measures soil’s acidity or alkalinity. The scale runs from 0 to 14 where 7 represents a neutral soil. Numbers below 7 indicate the degree of acidity, and numbers above 7 indicate the degree of alkalinity. The pH scale is logarithmic and each jump is a ten fold increase. A soil with a pH of 4 is 10 times for acidic than one with a pH of 5 and 100 times more acidic than one with a pH of 6.
Composting and the pH Factor
The microorganisms in compost operate best under neutral to acidic conditions with the pH in the range of 5 to 8. In the beginning stages of decomposition, organic acids are formed. Conditions that are acidic are best for the growth fungi and breakdown of lignin and cellulose. As composting goes on, the organic acids become neutralized. “Mature” compost generally has a pH between 6 and 8.
If there is not enough oxygen (anaerobic), the acid accumulation can lower the pH to 4.5 and limit microbial activity – thus slowing down the composting process. Aeration is needed to return the compost pH to an acceptable range.
Compost and Plants
Most garden plants do best in a slightly acidic to neutral soil – around pH 6.5 to 7. Compost can modify and stabilize pH. When compost is added to the soil, it acts as a chemical buffer and increases the plants tolerance to pH. Adding compost to a slightly alkaline soil will make it more neutral.
pH, STA Certification, and Aguinaga
Each month, Aguinaga sends a sample of compost to the US Composting Council where the pH and other properties are tested. By passing these lab tests every month, the US Composting Council awards us with the Seal of Testing Assurance (STA Certified.)

Aguinaga Materials Overview
General Ground Cover: 0-2 (particle size in inches)
Aguinaga ground covers are made from shredded tree trimmings and plant material that has been fully composted to STA standards established by the American Compost Council, which require the material to pass stringent testing after being exposed to 132degrees F for a period of time which eliminates seeds and pathogens. It is an economical, nitrogen stabilized material with a rich brown color that will preserve ground moisture, help prevent weeds, and add a pleasant contrast continuum to any garden area and deteriorates at a slow rate.
General Ground Cover: ½ to 1½ (particle size in inches)
This ground cover - similar to the one above but with a finer particle size - is made from native shredded tree trimmings and plant material. It is screened for uniformity, nitrogen stabilized and used for ground cover as well as for tree box mixes.
General Purpose Amendment (GPS2)
GPS2 is a fully composted soil amendment (thereby void of renegade seeds and deleterious pathogens) made from clean-green recycled material that can be used for back-fill material for planting shrubs and plants, or rototilled into the soil as a general amendment.
It is nitrogen stable – that is will not create nitrogen drag from the soil and plantings, and will generally achieve improved soil moisture retention in sandy soils and alleviate compaction in clay laden soils.
Planter Mix:
Planter mix is great for shallow planter boxes and color burst. It contains mature peat moss for micro nutrient supply as well as pearlite and redwood to help maintain moisture.
Seed Topper:
Seed topper, as the name implies is designed mainly to be used for covering seeds, but in many cases can be used as mulch, for planting mediums as a back-fill amendment. As a top dressing, the material can be used to dress walked-on corners, or for re-seeding turf.

Organic Matter Content
Organic matter content is the measure of the vast array of carbon based materials in compost and is typically expressed as a percentage of dry weight. Organic matter is an important ingredient in all soils and improves soil structure, physical condition, soil temperature, water holding capacity, and nutrient availability – especially the soil bacterial processes which affect the availability of mineral salts to plants.
High quality organic soil amendments should contain at least 40 percent organic matter. Soil and silica make up the remainder of the compost dry matter. The range for ideal organic matter content for compost ranges from 30 to 70 percent.
Being aware of a product's organic matter content is necessary for determining compost application rates on specific applications, such as soil incorporation, turf establishment, agricultural crop production, and topsoil production. Knowing the organic matter content is also useful for estimating the age and physical properties of the compost.
Each month, we send a sample of our compost to the US Composting Council lab where it is analyzed and tested. Organic matter content is one of the many properties that is tested.
