Plant Allelopathy

Plant Allelopathy

Plant allelopathy is the ‘chemical warfare’ among the plants imposed by one plant on another to suppress the latter and take advantage from that suppression. The word allelopathy comes from two Greek words allelon and pathos; where allelon means ‘each other’ and pathos means ‘to suffer’. Thus in the phenomenon of plant allelopathy, allelopathic plants create adverse conditions to other neighboring plants by reducing their seed germination and seedling growth. […]

Avocanoes at Zaytuna Farm

Avocanoes at Zaytuna Farm

Near Geoff and Nadia Lawton’s house at Zaytuna Farm, there are a number of Avocanoes… What on earth is an Avocanoe? Geoff and I came up with the concept of Avocanoes a little while ago. At the time, we were looking for a secure position to plant a number of expensive avocado trees. This location had a few requirements. 1. It had to be close to people for regular care. 2. Close to water supply. 3. And it must be close to material for budding and grafting of avocados by the plant nursery staff.

3 Nitrogen Fixing Trees for Snowy Regions

3 Nitrogen Fixing Trees for Snowy Regions

Nitrogen fixing trees are unique natural gifts that can solve the problem of nitrogen deficiency, one of the major problems of present world’s agriculture, without any potential ecological or environmental hazard. Apart from nitrogen addition to the soil, they are also capable of improving the quality of soils to a great extent; e.g. they can turn a disturbed soil into a good one. To facilitate their use in all types […]

Trees that are Great Soil Companions in Three Different Climates

Leucaena leucocephala02 - feat

Nitrogen fixing trees are the safest solution to the problem of nitrogen deficiency in present day’s agriculture. Nitrogen fixing tress can solve the problem by accumulating Nitrogen from the atmosphere and storing that within their body to use that themselves and release that into the soil for other neighbors. Though these trees don’t possess any danger for us like chemical fertilizers do, they may bring a total collapse to an […]

The Amazing, Multi-Functional Cohune Palm

The Amazing, Multi-Functional Cohune Palm

I first knowingly encountered the cohune palm in its tree form when looking for property in the far eastern region of Guatemala. They had thick bases, about half a meter across, and from there, immense fronds—some say the largest leaf in the world—stretch towards the jungle canopy. Ultimately, they fall short and wilt along the sides of the trunk.

Introducing Nitrogen Fixing Trees: Nature’s Solution to Curing N2 Deficiency

Casuarina

Nitrogen deficiency is a major challenge to world agriculture. This element is one of the most important nutrients for the growth and survival of plants. Roughly 78% of earth’s atmosphere consists of this gas essential to supporting life. However, plant life is unable to derive vital nutrients from its gaseous form. Instead, plants must pull nitrogen from their soil. The introduction of chemicals to compensate for nitrogen deficiency has created […]

The Boabs of Kimberley in the North West of Australia and the Bunyas of the north east coasts of Australia are two trees with outstanding appearance and function. These are two of my special interest trees the Boab Adansonia gegoeri and Bunya Araucaria bidwiili. My visits to the Kimberley began in the nineteen seventies and continued into the eighties. In the years 1999 to2003, I was living in the East […]

Touring the Cedars of Lebanon

Daniel Halsey, shows you the home of sustainable forestry for a thousand years, Lebanon has a history of foreign occupation, only matched by its resilient ability to maintain its resources in spite of political and social oppression. Imagine trees coppiced every 80 years, not annually or every few years. That takes dedication to long term sustainable practices, where generations honor a vision resources for their descendants and limit consumption. Some […]
