Aguinaga Green = Biosolid Free

According to the San Francisco Public Utilities Commission, biosolid compost comprises around 20 tons of the 82,000 tons of solid material removed from the city's sewer every year. The sludge goes to a composting facility where it is mixed with green waste and composted (heated to 130 degrees for 30 days.)

The San Francisco Chronical is reporting that a debate is going on over the safety of this biosolid compost.

Aguinaga Green does NOT use any biosolids in our products. All of our products are derived from tree trimmings and bush trimmings from local tree trimmers.

Cocoa Mulch can be dangerous for your pets

Make sure to buy your ground covers and mulches from Aguinaga Green. Our products are safe for your children and pets.

Cocoa mulch, which is sold at stores like Home Depot and other garden supply centers, can be dangerous to pets. Cocoa mulch contains theobromine and caffeine - two ingredients that could be fatal to dogs.

If a dog eats a few ounces of cocoa mulch, they could get stomach problems. It is especially dangerous for smaller breeds. Dogs may start to act restless and have seizures.

Cocoa mulch contains 300 to 1200 mg. of theobromine per ounce, which makes cocoa mulch one of the strongest concentrations of theobromine a pet may encounter.

All of Aguinaga's products are safe for your pets. Call us today at 1-877-OC-MULCH if you need ground cover or mulches. We also deliver.

Nitrolized Products

Aguinaga is proud to offer...

Nitrolized Fir Shavings: Nitrolized Fir Shavings are nitrogen fortified/stabilized to prevent drag (removal) from the soil. This product is particularly useful in sandy soil to aid in the retention of moisture, slowing percolation and leaching, and thereby aiding in the retention of nutrients.

Nitrolized Fir Chips: Nitrolized Fir Chips are nitrogen fortified/stabilized to prevent nitrogen drag from the soil. The particle size of this material is 3/8 minus and it is excellent as a soil amendment, improving the porosity for excellent drainage as well as good aeration in the soil. The product stands alone as a general soil amendment and is more resistant to decay than sawdust. It is also used as a supplement in other mixes.

See us at the Nursery Mart Show - June 2, 2010

Come visit us at the Nursery Mart Show!

The Nursery Mart will be in the building next to the California Grown Show.

The show is located at the Orange County Fairgrounds in Costa Mesa, California. Show hours are from 9am to 5pm.

You can register onsite the day of the show.

We look forward to seeing you!

There is no soil that can not be amended!

Clay laden soils cause difficulties in growing plants for several reasons - there is little oxygen within it, the impermeable character of the clay is a barrier to young propagating roots, it is sticky and hard to work with - and further, clay laden soil has a high alkalinity which is hard on roots.

When clay laden soil is mechanically broken up by tilling or spading, the loosened of the soil structure makes air pockets for much needed oxygen which is introduced - and when an amendment is added to the soil such as gypsum, further chemical remediation is added to the mix.

Gypsum is used both as a chemical and physical amendment for such soils. Sulphur is added from the gypsum, and the calcium in gypsum when mixed with water becomes soluble and is also taken up by the plant; both essentially for growth. The gypsum both mechanically and chemically breaks down the clay barrier to the plant growth and promotes porosity for drainage.

At Aguinaga Green, we contend that there is no soil that can not be amended!

GPS1 (general purpose soil amendment) is made from composted and totally "green" plant and tree cuttings. Visit either of our locations (East Orange or Irvine) to pick up some GPS1. We can load it right into your truck bed. We also deliver. Call 1-877-OC-MULCH for delivery prices or if you'd like some advice on how much product you need for your project. The general rule is that one cubic yard will cover approximately 100 square feet with three inches of material

Once you have the GPS1, you'll need to break up the top six inches of the clay soil. It's best to do this when the soil is dry, not wet. You can do this with a shovel or you can rent a tiller. Then add the GPS1 and mix it in. The area will be higher, and this will help with drainage.

Erosion testing with UC Riverside

Last summer, Aguinaga Green was ask to participate in erosion testing performed by the University of California – Riverside.

August 8th. 2009 a site was burned by members of the Riverside Fire Department and treatments were randomized within each of three rows with a variation in the compost application.

Two composting media were applied in different thickness. One consisted of “CLEAN GREEN COMPOSTED MATERIAL” and the other of “COMPOSTED BIOSOLID WASTE”
AGUINAGA GREEN provided all the clean green mulch for the project.

The testing plots are shown here on a hillside near the university - being discussed between AG and the university project manager. Rain events were monitored and runoff samples were collected from plastic bins following each storm event. Samples were analyzed for volume, pH, salinity, phosphorus, ammonia, nitrates, etc.

The sites were planted with seeds native to the area at twice the suggested rate per acre to assure a visually strong result.

Of great interest to us was that even after following the complete growing season – there was no result at all, on the biosolid plots - which is adequately shown even in the now-spent and cycled landscape test plots.

Our beliefs towards biosolids are further fortified that among other things that the salinity, heavy ammonia and phosphorus contained in this particular biosolid waste had an adverse impact – or curtailed the germination of the seeds spread under control in the project.
