Dinner

I haven't had a burger in months. As we walked past Burgerville on the way to the hotel my taste buds began to salivate. What joy when a brief Internet search revealed Burgerville's sustainability mission. Local grass fed meat. Take a look at their receipt. Wish all restaurants printed receipts like this.

Next food destination? I must find out where the pedestrian with her pink Voodoo Donuts' box has been.

Malawi to roll out "fertilizer trees" project

*Fertilizer trees should increase productivity of maize crops in Malawi

[BLANTYRE] Malawi will this year implement a 'fertilizer trees' project to reduce the amount of fertilizer needed by smallholder farmers.
Fertilizer trees are varieties of shrubs that capture nitrogen from the air and transfer it to the soil, a process known as nitrogen fixing. This restores nutrients and increases crop productivity — with potential to double or triple harvests.
The trees can be interplanted with crops for 1-3 years before being cut and left to decompose, providing fuel and more fertilizer.
Policymakers and agricultural scientists drew up plans for implementing the programme at a conference last month (13-16 February).
The project will target 200,000 farmers, representing ten per cent of the agricultural sector, and will start in August, according to Festus Akinnifesi, Malawi's senior tree scientist and country representative of the South African Development Community (SADC) and World Agroforestry Centre (ICRAF).
Akinnifesi says the farmers will receive free tree seeds, an information kit and training on the system and associated crop husbandry.

According to Jeffrey Sachs, director of the UN Millennium Project, fertilizer trees are among the most promising means for achieving the Millennium Development Goal of halving global hunger by 2015.
There are four fertilizer tree systems, all of which are based on improved fallowing ― allowing soil to recover nutrients. Malawi will adopt all four systems depending on the type of land.
The first system is sequential planting of nitrogen-fixing trees such as Sesbania sesban and Tephrosia vogelli with maize, shortening the amount of time land needs to lie fallow. In the second, Gliricidia sepium is planted along with maize and coppiced ― heavily pruned ― during maize growth to prevent competition.
The third involves planting nitrogen-fixing trees a few weeks after maize to reduce competition between the plants. In the fourth, leaves of trees are used as fertilizer for vegetable crop production in the wetlands and maize production in the uplands.

More than 300,000 farmers are currently using fertilizer trees in five SADC countries — Malawi, Mozambique, Tanzania, Zambia, and Zimbabwe.
